public abstract class XMPPProcessor
extends java.lang.Object
implements XMPPImplIfc, java.lang.Comparable<XMPPProcessor>

XMPPProcessor abstract class contains basic definition for XMPP processor. To create new processor implementing particular XMPP functionality it is enough to extend this class and implement one abstract method.
Additionally to allow system properly recognize this processor you need also to implement own constructor which sets proper values to parent constructor. You must implement exactly one constructor with zero parameters which calls parent constructor with proper values. Refer to constructor documentation for information about required parameters.
To fully interact with entity connected to the session or with other entities in XMPP network you should be also familiar with addReply(...), addMessage(...) and addBroadcast(...) methods.
There is also partialy implemented functionality to send messages to entities in other networks like SMTP or other implemented by the server. Once this implementation is finished there will be more information available. If you, however, are interested in this particular feature send a question to author.

Method Detail

supElements

public java.lang.String[] supElements()

Description copied from interface: XMPPImplIfc

Method supElements returns an array of element names for stanzas which can be processed by this plugin. Each element name corresponds to XMLNS returned in array by supNamespaces() method.

Specified by:

supElements in interface XMPPImplIfc

Returns:

a String[] value

supNamespaces

public java.lang.String[] supNamespaces()

Description copied from interface: XMPPImplIfc

Method supNamespaces returns an array of namespaces for stanzas which can be processed by this pluing. Each namespace corresponds to element name returned in array by supElemenets() method.

Specified by:

supNamespaces in interface XMPPImplIfc

Returns:

a String[] value

supStreamFeatures

public tigase.xml.Element[] supStreamFeatures(XMPPResourceConnection session)

Description copied from interface: XMPPImplIfc

Method supStreamFeatures returns an array of XML Elements with stream features which have to be returned to the client uppon request. Stream features returned by this method correspond to features supported by this plugin.

Specified by:

supStreamFeatures in interface XMPPImplIfc

Parameters:

session - a XMPPResourceConnection value

Returns:

an Element[] value

supDiscoFeatures

public tigase.xml.Element[] supDiscoFeatures(XMPPResourceConnection session)

Description copied from interface: XMPPImplIfc

Method supDiscoFeatures returns an array of XML Elements with service discovery features which have to be returned to the client uppon request. Service discovery features returned by this method correspond to services supported by this plugin.

Specified by:

supDiscoFeatures in interface XMPPImplIfc

Parameters:

session - a XMPPResourceConnection value

Returns:

an Element[] value

isSupporting

public boolean isSupporting(java.lang.String element,
                            java.lang.String ns)

Description copied from interface: XMPPImplIfc

Method isSupporting takes element name and namespace for this element and determines whether this element can be processed by this plugin.

Specified by:

isSupporting in interface XMPPImplIfc

Parameters:

element - a String value

ns - a String value

Returns:

a boolean value

getInstance

public XMPPProcessor getInstance()

compareTo

public final int compareTo(XMPPProcessor proc)

Method compareTo is used to perform

Specified by:

compareTo in interface java.lang.Comparable<XMPPProcessor>

Parameters:

proc - an XMPPProcessor value

Returns:

an int value

init

public void init(UserRepository rep)
          throws TigaseDBException

Description copied from interface: XMPPImplIfc

Method init is called just after the plugin has been loaded into memory. The idea behind this is to allow it to initialize or check the database. This might be especially useful for plugins which want to have a database access via non-standard stored procedures or need schema upgrade.

Specified by:

init in interface XMPPImplIfc

Parameters:

rep - an UserRepository value

Throws:

TigaseDBException
