AnyEvent::XMPP::Component - "XML" stream that implements the XEP-0114

SYNOPSIS

Top

   use AnyEvent::XMPP::Component;

   my $con = AnyEvent::XMPP::Component->new (
                domain => 'chat.jabber.org'
                host   => 'jabber.org',
                port   => 5347,
                secret => 'insecurepasswordforthehackers'
             );
   $con->reg_cb (session_ready => sub { ... });
   $con->connect;

DESCRIPTION

Top

This module represents a XMPP connection to a server that authenticates as component.

This module is a subclass of AnyEvent::XMPP::Connection and inherits all methods. For example reg_cb and the stanza sending routines.

For additional events that can be registered to look below in the EVENTS section.

Please note that for component several functionality in AnyEvent::XMPP::Connection might have no effect or not the desired effect. Basically you should use the AnyEvent::XMPP::Component as component and only handle events the handle with incoming data. And only use functions that send stanzas.

No effect has the event stream_pre_authentication and the authenticate method of AnyEvent::XMPP::Connection, because those handle the usual SASL or iq-auth authentication. "Jabber" components have a completly different authentication mechanism.

Also note that the support for some XEPs in AnyEvent::XMPP::Ext is just thought for client side usage, if you miss any functionaly don't hesitate to ask the author or send him a patch! (See AnyEvent::XMPP for contact information).

METHODS

Top

new (%args)

This is the constructor. It takes the same arguments as the constructor of AnyEvent::XMPP::Connection along with a few others:

NOTE: Please note that some arguments that AnyEvent::XMPP::Connection usually takes have no effect when using this class. (That would be the 'username', 'password', 'resource' and 'jid' arguments for example.)

secret => $secret

$secret is the secret that will be used for authentication with the server.

EVENTS

Top

These additional events can be registered on with reg_cb:

NOTE: The event stream_pre_authentication should _not_ be handled and just ignored. Don't attach callbacks to it!

session_ready

This event indicates that the component has connected successfully and can now be used to transmit stanzas.
