The XMPP stanza C{iq} has a request-response nature that fits naturally with deferreds. You send out a request and when the response comes back a deferred is fired. The L{twisted.words.protocols.jabber.client.IQ} class implements a C{send} method that returns a deferred. This deferred is put in a dictionary that is kept in an L{XmlStream} object, keyed by the request stanzas C{id} attribute. An object providing this interface (usually an instance of L{XmlStream}), keeps the said dictionary and sets observers on the iq stanzas of type C{result} and C{error} and lets the callback fire the associated deferred. z2Dictionary of deferreds waiting for an iq responseN)r r r r r �iqDeferredsr r r r r # s r c @ sP e Zd ZdZed�Zed�Zdd� Zdd� Zdd � Z d d� Z dd � Zdd� ZdS )�IXMPPHandlerz� Interface for XMPP protocol handlers.
