Member Function Documentation

clone()

virtual StanzaExtension* clone ( ) const

inlinevirtual

Returns an identical copy of the current StanzaExtension.

Returns

An identical copy of the current StanzaExtension.

Implements StanzaExtension.

Definition at line 326 of file disco.h.

filterString()

const std::string & filterString ( ) const

virtual

Returns an XPath expression that describes a path to child elements of a stanza that an extension handles.

Returns

The extension's filter string.

Implements StanzaExtension.

Definition at line 221 of file disco.cpp.

items()

const ItemList& items ( ) const

inline

Returns the entity's/node's items.

Returns

A list of pointers to Item objects.

Definition at line 311 of file disco.h.

newInstance()

virtual StanzaExtension* newInstance ( const Tag *  tag ) const

inlinevirtual

Returns a new Instance of the derived type. Usually, for a derived class FooExtension, the implementation of this function looks like:

StanzaExtension* FooExtension::newInstance( const Tag* tag ) const
{
  return new FooExtension( tag );
}

Returns

The derived extension's new instance.

Implements StanzaExtension.

Definition at line 317 of file disco.h.

node()

const std::string& node ( ) const

inline

Returns the queried node identifier, if any.

Returns

The node identifier. May be empty.

Definition at line 305 of file disco.h.

setItems()

void setItems

(

const ItemList &

items

)

This function can be used to set the entity's/node's items.

Parameters

items

A list of pointers to the entity's/node's items.

Note

The Item objects pointed to will be owned by the Items object. The list should neither be used again nor should the Item objects be deleted.

Definition at line 214 of file disco.cpp.

tag()

Tag * tag ( ) const

virtual

Returns a Tag representation of the extension.

Returns

A Tag representation of the extension.
