public class Rss
extends java.lang.Object

The RSS Bean is used to retrieve, parse, and write RSS syndicated content.

The RSS Bean implements a standard RSS newsreader with extended capabilities as specified at http://backend.userland.com/rss2.

The bean contains a number of properties that map directly to RSS fields. To receive a feed call the GetFeed method with the URL or file to retrieve specified in the URL parameter. The RSS bean can also generate RSS feeds, which can be retrieved through the RSSData property or written through the WriteFile method.

The RSS Bean supports all RSS feed properties that are standard in versions 0.91, 0.92 and 2.0 of the RSS protocol through a number of bean properties. It also supports non-standard properties as specified in the RSS protocol through the Namespaces collection and the GetProperty and SetProperty methods.

Method Detail

getAccept

public java.lang.String getAccept()
A list of acceptable MIME types for the request.

If this property contains a non-empty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.


setAccept

public void setAccept(java.lang.String accept)
               throws IPWorksException
A list of acceptable MIME types for the request.

If this property contains a non-empty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.

Throws:
IPWorksException

getAuthorization

public java.lang.String getAuthorization()
The Authorization string to be sent to the server.

If the Authorization property contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP bean can be extended with other security schemes in addition to the authorization schemes already implemented by the bean.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".


setAuthorization

public void setAuthorization(java.lang.String authorization)
                      throws IPWorksException
The Authorization string to be sent to the server.

If the Authorization property contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP bean can be extended with other security schemes in addition to the authorization schemes already implemented by the bean.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

Throws:
IPWorksException

getAuthScheme

public int getAuthScheme()
The authentication scheme to use when server authorization is required.

This property will tell the bean which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the bean will attempt basic authentication. If AuthScheme is set to authDigest (1), authNtlm (4) or authNegotiate (5), digest, NTLM or Negotiate authentication will be attempted instead.

If AuthScheme is set to authProprietary (2) then the authorization token must be supplied through Authorization property.

If AuthScheme is set to authOAuth (6) then the authorization string must be supplied through Authorization property.

Note that, if you set the Authorization property and AuthScheme is not authProprietary or authOAuth, the AuthScheme will be set automatically to authProprietary (2) by the control.

For security purposes, changing the value of this property will cause the bean to clear the values of User , Password and Authorization .


setAuthScheme

public void setAuthScheme(int authScheme)
                   throws IPWorksException
The authentication scheme to use when server authorization is required.

This property will tell the bean which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the bean will attempt basic authentication. If AuthScheme is set to authDigest (1), authNtlm (4) or authNegotiate (5), digest, NTLM or Negotiate authentication will be attempted instead.

If AuthScheme is set to authProprietary (2) then the authorization token must be supplied through Authorization property.

If AuthScheme is set to authOAuth (6) then the authorization string must be supplied through Authorization property.

Note that, if you set the Authorization property and AuthScheme is not authProprietary or authOAuth, the AuthScheme will be set automatically to authProprietary (2) by the control.

For security purposes, changing the value of this property will cause the bean to clear the values of User , Password and Authorization .

Throws:
IPWorksException

getChannel

public RSSChannel getChannel()

This property contains fields which contain values for sub-elements of the RSS Channel .


setChannel

public void setChannel(RSSChannel channel)
                throws IPWorksException
The channel data for the feed.

This property contains fields which contain values for sub-elements of the RSS Channel .

Throws:
IPWorksException

isConnected

public boolean isConnected()
Shows whether the bean is connected.

This property is used to determine whether or not the bean is connected to the remote host.


setConnected

public void setConnected(boolean connected)
                  throws IPWorksException
Shows whether the bean is connected.

This property is used to determine whether or not the bean is connected to the remote host.

Throws:
IPWorksException

getCookies

public HTTPCookieList getCookies()
Collection of cookies.

This property contains a collection of cookies. To add cookies to outgoing HTTP requests, add cookies (of type httpcookie ) to this collection.

To see cookies that are set by the server, use the SetCookie event, which displays the cookies and their properties as set by the server. Those cookies are also added to Cookies .

MaxHTTPCookies can be used to control the maximum number of cookies saved.

This collection is indexed from 0 to size - 1.


getFirewall

public Firewall getFirewall()
A set of properties related to firewall access.

This is a Firewall type property which contains fields describing the firewall through which the bean will attempt to connect.


setFirewall

public void setFirewall(Firewall firewall)
                 throws IPWorksException
A set of properties related to firewall access.

This is a Firewall type property which contains fields describing the firewall through which the bean will attempt to connect.

Throws:
IPWorksException

getFollowRedirects

public int getFollowRedirects()
Determines what happens when the server issues a redirect.

This property determines what happens when the server issues a redirect. Normally, the bean returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same, otherwise the bean throws an exception.

Note that following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless this property is set to frAlways (1), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the bean throws an exception instead.


setFollowRedirects

public void setFollowRedirects(int followRedirects)
                        throws IPWorksException
Determines what happens when the server issues a redirect.

This property determines what happens when the server issues a redirect. Normally, the bean returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same, otherwise the bean throws an exception.

Note that following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless this property is set to frAlways (1), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the bean throws an exception instead.

Throws:
IPWorksException

isIdle

public boolean isIdle()
The current status of the component.

Idle will be False if the component is currently busy (communicating and/or waiting for an answer), and True at all other times.


getIfModifiedSince

public java.lang.String getIfModifiedSince()
A date determining the maximum age of the desired document.

If this property contains a non-empty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the bean throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. An example is Sat, 29 Oct 1994 19:43:31 GMT.


setIfModifiedSince

public void setIfModifiedSince(java.lang.String ifModifiedSince)
                        throws IPWorksException
A date determining the maximum age of the desired document.

If this property contains a non-empty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the bean throws an exception

Throws:
IPWorksException

getItems

public RSSItemList getItems()
A collection of items in the current RSS feed.

This property contains a collection of items in the current RSS channel. When an RSS feed is parsed by the component, all of the items in the feed are stored as rssitem types in this collection.

This collection can also be populated before writing an RSS feed with WriteFile .

This collection is indexed from 0 to size - 1.


getLocalFile

public java.lang.String getLocalFile()
The path to a local file for downloading. If the file exists, it is overwritten.

This property is used when getting a document.

If this property is empty then the received data is provided through TransferredData and the Transfer event.


setLocalFile

getLocalHost

public java.lang.String getLocalHost()
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the bean initiate connections (or accept in the case of server beans) only through that interface.

If the bean is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.


setLocalHost

public void setLocalHost(java.lang.String localHost)
                  throws IPWorksException
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the bean initiate connections (or accept in the case of server beans) only through that interface.

If the bean is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Throws:
IPWorksException

getNamespaces

public XMLNamespaceList getNamespaces()
A collection of namespaces in the current namespace stack.

This property contains a list of the XML namespaces that exist in the current RSS channel. Each version of the RSS protocol defines a specific set of standard RSS feed properties. However, the general RSS protocol allows non-standard fields to be added through XML namespaces.

When parsing an RSS feeds retrieved through the GetFeed method, the bean will store all properties that are standard in version 2.0 of the RSS protocol, regardless of the version given by the feed. For non-standard properties, it will verify that the property has a namespace and that the namespace is defined within the RSS feed. If a property's definition cannot be found, the bean throws an exception. Non-standard fields can be retrieved through the GetProperty method.

When using the WriteFile method to generate an RSS feed that contains non-standard properties you must use the SetProperty method to set each non-standard property. The bean will ignore any property whose namespace is not defined when generating the RSSData .

Please see the GetProperty and SetProperty methods for details on argument syntax.


getOtherHeaders

public java.lang.String getOtherHeaders()
Other headers as determined by the user (optional).

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties like ContentType , From , etc.

The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\\r\\n") .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the bean beyond what is provided.

Throws:
IPWorksException

getParsedHeaders

public HeaderList getParsedHeaders()
Collection of headers returned from the last request.

This property contains a collection of headers returned from the last request. Whenever headers are returned from the server, the headers are parsed into a collection of headers. Each header in this collection contains information describing that header.

MaxHeaders can be used to control the maximum number of headers saved.

This collection is indexed from 0 to size - 1.


getPassword

public java.lang.String getPassword()

The bean will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the bean throws an exception.

Please note that by default, all timeouts are inactivity timeouts , i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

Optionally, the behavior of the bean may be changed to absolute timeouts , i.e. the bean will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the AbsoluteTimeout configuration setting.

The default value for the Timeout property is 60 (seconds).


setTimeout

public void setTimeout(int timeout)
                throws IPWorksException
A timeout for the bean.

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the bean will wait for the operation to complete before returning control.

IPWorksException

getTransferredData

public byte[] getTransferredData()
The contents of the last response from the server.

This property contains the contents of the last response from the server. If the LocalFile is empty, the data is accumulated in TransferredData , and can also be received in the Transfer event. Otherwise, this property returns an empty string.

TransferredDataLimit controls the maximum amount of data accumulated in TransferredData (by default there is no limit).


getTransferredDataLimit

public long getTransferredDataLimit()
The maximum of bytes of data to be transferred.

This property defines the maximum of bytes of data to be transferred. The default value is 0, which means there is no limit to the amount of data the bean will accumulate and parse. If this value is set to a number n which is greater than 0, the bean will only receive the first n bytes of data from the server.


setTransferredDataLimit

public void setTransferredDataLimit(long transferredDataLimit)
                             throws IPWorksException

IPWorksException

config

public java.lang.String config(java.lang.String configurationString)
                        throws IPWorksException
Sets or retrieves a configuration setting.

Config is a generic method available in every bean. It is used to set and retrieve configuration settings for the bean.

Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the bean, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY , you must call Config("PROPERTY=VALUE") , where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY") . The value will be returned as a string.

The bean accepts one or more of the following configuration settings . Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the bean, access to these internal properties is provided through the Config method.

RSS Configuration Settings

MaxItems
Instructs bean to save the amount of specified that are parsed from the rss feed
This config should be set when the Items collection will be populated when a feed is being parsed by the bean. This value represents the number of items that are to be saved in the collection .To save all items to the collection , set this config to -1. If no items are wanted, set this to 0, which will not save any to the collection . The default for this config is -1, so all items will be included in the collection .

NOTE: This functionality is only available in Java and .NET.

ItemAdditionalData[i]
Additional data to be added to an RSS Feed item
This config allows you to specify additional data to be added to an RSS Feed item.Valid array indices are from 0 to Items .Count - 1.

Note: This config is write-only and no validation is performed on the specified data.

ValueFormat
Format of data returned or set
This config specifies the format of the data set or received into/from XML value properties.The following are the possible values:
0 (vfText)
Textual data. Any '<', '>', and '&' characters are escaped to '&lt;', '&gt;', and '&amp;'.
1 (vfXML)
XML data. No escaping is performed.

HTTP Configuration Settings

AcceptEncoding
Used to tell the server which types of content encodings the client supports
When AllowHTTPCompression is true, the bean adds an "Accept-Encoding: " header to the request being sent to the server. By default, this header's value is "gzip, deflate". This config allows you to change the value of the "Accept-Encoding" header. NOTE: The bean only supports gzip and deflate decompression algorithms.
AllowHTTPCompression
This property enables HTTP compression for receiving data
This is the same as the AllowHTTPCompression property. This setting is exposed here for use by beans that inherit from HTTP.
Authorization
The Authorization string to be sent to the server
If the Authorization property contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.This property is provided so that the HTTP bean can be extended with other security schemes in addition to the authorization schemes already implemented by the bean.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

BytesTransferred
Contains the number of bytes transferred in the response data
Returns the raw number of bytes from the HTTP response data, prior to the component processing the data, whether it is chunked and/or compressed. This returns the same value as the Transfer event, by BytesTransferred .
EncodeURL
If set to true the URL will be encoded by the bean
The default value is false. If set to true the URL passed to the bean will be URL encoded.
GetOn302Redirect
If set to true the bean will perform a GET on the new location
The default value is false. If set to true the bean will perform a GET on the new location. Otherwise it will use the same HTTP method again.
HTTPVersion
The version of HTTP used by the bean
Possible values include "1.0", and "1.1". The default is "1.1".
IfModifiedSince
A date determining the maximum age of the desired document
This is the same as the IfModifiedSince property. This setting is exposed here for use by beans that inherit from HTTP.
KeepAlive
Determines whether the HTTP connection is closed after completion of the request
If true, the component will not send the 'Connection: Close' header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note that not all server support persistent connections. You may also explicitly add the Keep-Alive header to the request headers by setting OtherHeaders to 'Connection: Keep-Alive'. If false, the connection will be closed immediately after the server response is received.The default value for KeepAlive is false.

MaxHeaders
Instructs bean to save the amount of headers specified that are returned by the server after a Header event has been fired
This config should be set when the TransferredHeaders collection is to be populated when a Header event has been fired. This value represents the number of headers that are to be saved in the collection.To save all items to the collection , set this config to -1. If no items are wanted, set this to 0, which will not save any to the collection . The default for this config is -1, so all items will be included in the collection .

NOTE: This functionality is only available in Java and .NET.

MaxHTTPCookies
Instructs bean to save the amount of cookies specified that are returned by the server when a SetCookie event is fired
This config should be set when populating the Cookies collection as a result of an HTTP request. This value represents the number of cookies that are to be saved in the collection .To save all items to the collection , set this config to -1. If no items are wanted, set this to 0, which will not save any to the collection . The default for this config is -1, so all items will be included in the collection .

NOTE: This functionality is only available in Java and .NET.

MaxRedirectAttempts
Limits the number of redirects that are followed in a request
When FollowRedirects is set to any value besides frNever the bean will follow redirects until this maximum number of redirect attempts are made. The default value is 20. \011
ProxyAuthorization
The authorization string to be sent to the proxy server
Similar to the Authorization config, but for proxy authorization. If this config contains a non-empty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy authorization information to the server. If User and Password are specified, this value is calculated using the algorithm specified by AuthScheme .
ProxyAuthScheme
The authorization scheme to be used for the proxy
This is the same as AuthScheme . This setting is provided for use by beans that do not directly expose Proxy properties.
ProxyPassword
A password if authentication is to be used for the proxy
This is the same as Password . This setting is provided for use by beans that do not directly expose Proxy properties.
ProxyPort
Port for the proxy server (default 80)
This is the same as Port . This setting is provided for use by beans that do not directly expose Proxy properties.
ProxyServer
Name or IP address of a proxy server (optional)
This is the same as Server . This setting is provided for use by beans that do not directly expose Proxy properties.
ProxyUser
A user name if authentication is to be used for the proxy
This is the same as User . This setting is provided for use by beans that do not directly expose Proxy properties.
TransferredDataLimit
The maximum number of incoming bytes to be stored by the bean
The default value is 65,536, allowing the bean to accumulate the first 64K of data into the TransferredData buffer.If TransferredDataLimit is set to 0, no limits are imposed.

UseChunkedEncoding
Enables or Disables HTTP chunked encoding for transfers
If UseChunkedEncoding is set to true, the bean will use HTTP chunked encoding when posting if possible. HTTP chunked encoding allows large files to be sent in chunks instead of all at once. If set to false, the bean will not use HTTP chunked encoding. The default value is false. Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

ChunkSize
Specifies the chunk size in bytes when using chunked encoding
This is only applicable when UseChunkedEncoding is true. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.
UsePlatformHTTPClient
Whether or not to use the platform HTTP client
If True, the component will use the default HTTP client for the platform ( URLConnection in Java or WebRequest in .NET) instead of the internal HTTP implementation. This is important for environments where direct access to sockets is limited or not allowed (as in the Google AppEngine for instance).
UserAgent
Information about the user agent (browser)
This is the value supplied in the HTTP User-Agent header. The default setting is "/n software IPWorks HTTP/S Component - www.nsoftware.com".Override the default with the name and version of your software.

KerberosSPN
The Service Principal Name for the Kerberos Domain Controller
If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

IPPort Configuration Settings

FirewallAutoDetect
Tells the bean whether or not to automatically detect and use firewall system settings, if available
This is the same as AutoDetect . This setting is provided for use by beans that do not directly expose Firewall properties.
FirewallHost
Name or IP address of firewall (optional)
If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This is the same as Host . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallListener
If true, the component binds to a SOCKS firewall as a server (IPPort only)
This entry is for IPPort only and does not work for other components that descend from IPPort.If this entry is set, the bean acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost , and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

FirewallPassword
Password to be used if authentication is to be used when connecting through the firewall
If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the bean throws an exception.NOTE: This is the same as Password . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallPort
The TCP port for the FirewallHost;
Note that the FirewallPort is set automatically when FirewallType is set to a valid value.NOTE: This is the same as Port . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallType
Determines the type of firewall to connect through
The appropriate values are as follows:
0
No firewall (default setting).
1
Connect through a tunneling proxy. FirewallPort is set to 80.
2
Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3
Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
NOTE: This is the same as FirewallType . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallUser
A user name if authentication is to be used connecting through a firewall
If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the bean throws an exception.NOTE: This is the same as User . This setting is provided for use by beans that do not directly expose Firewall properties.

KeepAliveTime
The inactivity time in milliseconds before a TCP keep-alive packet is sent
When set, TCPKeepAlive will automatically be set to true. By default the operating system will determine the time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.Note: This value is not applicable in Java.

KeepAliveInterval
The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received
When set, TCPKeepAlive will automatically be set to true. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime . If no acknowledgement is received from the remote host the keep-alive packet will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.Note: This value is not applicable in Java or MAC.

Linger
When set to True, connections are terminated gracefully
This property controls how a connection is closed. The default is True.In the case that Linger is True (default), there are two scenarios for determining how long the connection will linger. The first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP protocol timeout expires.

In the second scenario, LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the bean returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.

LingerTime
Time in seconds to have the connection linger
LingerTime is the time, in seconds, to leave the socket connection linger. This value is 0 by default, which means it will use the default IP protocol timeout.
LocalHost
The name of the local host through which connections are initiated or accepted
The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the bean initiate connections (or accept in the case of server beans) only through that interface.

If the bean is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort
The TCP port in the local host where the bean binds
This must be set before a connection is attempted. It instructs the bean to bind to a specific port (or communication endpoint) in the local machine.Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength
The maximum amount of data to accumulate when no EOL is found
MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes. The maximum value is 65536 bytes.

MaxTransferRate
The transfer rate limit in bytes per second
This setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default this is not set and there is no limit.
TCPKeepAlive
Determines whether or not the keep alive socket option is enabled
If set to true, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.Note: This value is not applicable in Java.

UseIPv6
Whether or not to use IPv6
By default, the component expects an IPv4 address for local and remote host properties, and will create an IPv4 socket. To use IPv6 instead, set this to True.
CloseStreamAfterTransfer
If true, the component will close the upload or download stream after the transfer
This entry is for bean and all the components that descend from it.This property is true by default. Therefore, by default, all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, you must set this config to false.

TcpNoDelay
Whether or not to delay when sending packets
When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.By default, this config is set to false.

Socket Configuration Settings

AbsoluteTimeout
Determines whether timeouts are inactivity timeouts or absolute timeouts
If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.
FirewallData
Used to send extra data to the firewall
When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).
InBufferSize
The size in bytes of the incoming queue of the socket
This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the bean is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize
The size in bytes of the outgoing queue of the socket
This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the bean is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Configuration Settings

GUIAvailable
Tells the bean whether or not a message loop is available for processing events
In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The bean will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.In some non-GUI applications an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GuiAvailable to false will ensure that the bean does not attempt to process external events.

Throws:
IPWorksException

doEvents

public void doEvents()
              throws IPWorksException
Processes events from the internal message queue.

When DoEvents is called, the bean processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Throws:
IPWorksException

getFeed

public void getFeed(java.lang.String URL)
             throws IPWorksException
Fetches an RSS feed.

This method fetches documents using the HTTP GET method. The document contents are delivered in the RSSData property, as well as through the Transfer event, and the HTTP response headers through the Header event. If the LocalFile property has been set, the bean will write the transferred data there.

The bean will then attempt to parse the RSS feed, filling in the Channel and Item properties as it goes. The feed properties can be accessed either directly through the named properties, or through the GetProperty and SetProperty methods.

Throws:
IPWorksException

getProperty

public java.lang.String getProperty(java.lang.String propertyName)
                             throws IPWorksException
Gets the value of a specific RSS feed item element or attribute.

This method is intended for extending functionality of the RSS bean. It will get the value for a specific item element or attribute of this RSS feed. Property is the XPath of the element or attribute according to the following convention: root/element@attribute . The @attribute part is optional, and the root field can be any of the four following values:

channel
This treats the channel as the root level, and element is any property of the channel. If the empty string ("") is supplied for the root field, the bean will assume channel as the root.
image
This treats the channel's image as the root level, and element is any property of an image.
textInput
This treats the channel's textInput as the root level, and element is any property of an textInput.
item[x]
This treats the channel's xth item as the root level where the indexer x starts at 1. The field element is any property of an item.

The element field can be any property of the root field, and attribute can be any property of that field. If an attribute is not supplied, this method will return the text portion of element . For example:

 RSSControl.GetProperty("item[5]/guid@isPermaLink")
   RSSControl.GetProperty("item[5]/link")
   RSSControl.GetProperty("/channel/title") 

Note : in order to add non-standard fields (i.e. fields that are not defined in the RSS specification), element must be prefixed with a namespace that defines that field. The same applies for the attribute field. Use the Namespaces collection to define and list namespaces.

Throws:
IPWorksException

getURL

public void getURL(java.lang.String URL)
            throws IPWorksException
Fetches an RSS feed.

This method fetches the document using the HTTP GET method. The document contents are delivered in the RSSData property, as well as through the Transfer event, and the HTTP response headers through the Header event. If the LocalFile property has been set, the bean will write the transferred data there.

The bean will not parse the data returned by the server. For more control over the retrieval of the item link, please use the HTTP bean.

Throws:
IPWorksException

interrupt

public void interrupt()
               throws IPWorksException
Interrupt the current method.

If there is no method in progress, Interrupt simply returns, doing nothing.

public java.lang.String OPMLAttr(java.lang.String attrName)
                          throws IPWorksException
Returns the value of the attribute specified in the parameter.

This method may be used to get the value of an attribute for an outline entry of an OPML document. The attribute desired must be specified in the parameter of this method. Also, this method must be invoked inside the OPMLOutline event.

Throws:
IPWorksException

put

public void put(java.lang.String URL)
         throws IPWorksException
Sends data to the HTTP server using the HTTP PUT method.

This method sends data to the HTTP server. The data is taken from PostData and/or AttachedFile properties. The server response text is received through the Transfer event, and the HTTP response headers through the Header event. If LocalFile is not empty the data (not the headers) is written there as well. The user should normally have assigned correct values to User and Password or Authorization .

Throws:
IPWorksException

readFile

public void readFile(java.lang.String fileName)
              throws IPWorksException
Loads an RSS file into the bean.

                 throws IPWorksException
Sets the value of a specific RSS feed property.

This method is intended for extending functionality of the RSS bean. It will set the value for a specific field of this RSS feed. Property is the name of the property according to the following convention: root/element@attribute . The root field can be any of the four following values:

channel
This treats the channel as the root level, and element is any property of the channel. If the empty string ("") is supplied for the root field, the bean will assume channel as the root.
image
This treats the channel's image as the root level, and element is any property of an image.
textInput
This treats the channel's textInput as the root level, and element is any property of an textInput.
item[x]
This treats the channel's x-th item as the root level The field element is any property of an item.

The element field can be any property of the root field, and attribute can be any property of that field. If an attribute is not supplied, Value will be placed in the text portion of element . For example:

 RSSControl.SetProperty("item[5]/guid@isPermaLink", "true") 

Note : in order to add non-standard fields (i.e. fields that are not defined in the RSS specification), element must be prefixed with a namespace that defines that field. The same applies for the attribute field. Use the Namespaces collection to define and list namespaces.
