NAME ^

AnyEvent::XMPP::IM::Connection - "XML" stream that implements the XMPP RFC 3921.

SYNOPSIS ^

   use AnyEvent::XMPP::Connection;

   my $con = AnyEvent::XMPP::Connection->new;

DESCRIPTION ^

This module represents a XMPP instant messaging connection and implements RFC 3921.

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.

METHODS ^

new (%args)

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

dont_retrieve_roster => $bool

Set this to a true value if no roster should be requested on connection establishment. You can retrieve the roster later if you want to with the retrieve_roster method.

The internal roster will be set even if this option is active, and even presences will be stored in there, except that the get_contacts method on the roster object won't return anything as there are no roster items.

initial_presence => $priority

This sets whether the initial presence should be sent. $priority should be the priority of the initial presence. The default value for the initial presence $priority is 10.

If you pass a undefined value as $priority no initial presence will be sent!

retrieve_roster ($cb)

This method initiates a roster request. If you set dont_retrieve_roster when creating this connection no roster was retrieved. You can do that with this method. The coderef in $cb will be called after the roster was retrieved.

The first argument of the callback in $cb will be the roster and the second will be a AnyEvent::XMPP::Error::IQ object when an error occurred while retrieving the roster.

get_roster

Returns the roster object of type AnyEvent::XMPP::IM::Roster.

EVENTS ^

These additional events can be registered on with reg_cb:

In the following events $roster is the AnyEvent::XMPP::IM::Roster object you get by calling get_roster.

NODE: The first argument to each callback is always the AnyEvent::XMPP::IM::Connection object itself. Also see Object::Event for more information about registering callbacks.

session_ready

This event is generated when the session has been fully established and can be used to send around messages and other stuff.

session_error => $error

If an error happened during establishment of the session this event will be generated. $error will be an AnyEvent::XMPP::Error::IQ error object.

roster_update => $roster, $contacts

This event is emitted when a roster update has been received. $contacts is an array reference of AnyEvent::XMPP::IM::Contact objects which have changed. If a contact was removed it will return 'remove' when you call the subscription method on it.

The first time this event is sent is when the roster was received for the first time.

roster_error => $error

If an error happened during retrieval of the roster this event will be generated. $error will be an AnyEvent::XMPP::Error::IQ error object.

presence_update => $roster, $contact, $old_presence, $new_presence

This event is emitted when the presence of a contact has changed. $contact is the AnyEvent::XMPP::IM::Contact object which presence status has changed. $old_presence is a AnyEvent::XMPP::IM::Presence object which represents the presence prior to the change. $new_presence is a AnyEvent::XMPP::IM::Presence object which represents the presence after to the change. The new presence might be undef if the new presence is 'unavailable'.

presence_error => $error

This event is emitted when a presence stanza error was received. $error will be an AnyEvent::XMPP::Error::Presence error object.

message => $msg

This event is emitted when a message was received. $msg is a AnyEvent::XMPP::IM::Message object.

message_error => $error

This event is emitted when a message stanza error was received. $error will be an AnyEvent::XMPP::Error::Message error object.

contact_request_subscribe => $roster, $contact, $message

This event is generated when the $contact wants to subscribe to your presence.

If you want to accept or decline the request, call send_subscribed method of AnyEvent::XMPP::IM::Contact or send_unsubscribed method of AnyEvent::XMPP::IM::Contact on $contact.

If you want to start a mutual subscription you have to call send_subscribe AFTER you accepted or declined with send_subscribed/send_unsubscribed. Calling it in the opposite order gets some servers confused!

If a status element was transmitted with the subscription it's contents will be in $message. Which is usually a text written from the one who requests subscription.

contact_subscribed => $roster, $contact, $message

This event is generated when $contact subscribed you to his presence successfully.

If a status element was transmitted with the subscribed presence it's contents will be in $message.

contact_did_unsubscribe => $roster, $contact, $message

This event is generated when $contact unsubscribes from your presence.

If you want to unsubscribe from him call the send_unsubscribe method of AnyEvent::XMPP::IM::Contact on $contact.

If a status element was transmitted with the unsubscription it's contents will be in $message. Which is usually a text written from the one who unsubscribes.

contact_unsubscribed => $roster, $contact, $message

This event is generated when $contact unsubscribed you from his presence.

If you want to unsubscribe him from your presence call the send_unsubscribed method of AnyEvent::XMPP::IM::Contact on $contact.

If a status element was transmitted with the unsubscription it's contents will be in $message.
