NAME

AnyEvent::XMPP::IM::Roster - Instant messaging roster for XMPP

SYNOPSIS

my $con = AnyEvent::XMPP::IM::Connection->new (...);
...
my $ro  = $con->roster;
if (my $c = $ro->get_contact ('test@example.com')) {
   $c->make_message ()->add_body ("Hello there!")->send;
}

DESCRIPTION

This module represents a class for roster objects which contain contact information.

It manages the roster of a JID connected by an AnyEvent::XMPP::IM::Connection. It manages also the presence information that is received.

You get the roster by calling the roster method on an AnyEvent::XMPP::IM::Connection object. There is no other way.

METHODS

is_retrieved

Returns true if this roster was fetched from the server or false if this roster hasn't been retrieved yet.

new_contact ($jid, $name, $groups, $cb)

This method sends a roster item creation request to the server. $jid is the JID of the contact. $name is the nickname of the contact, which can be undef. $groups should be a array reference containing the groups this contact should be in.

The callback in $cb will be called when the creation is finished. The first argument will be the AnyEvent::XMPP::IM::Contact object if no error occured. The second argument will be an AnyEvent::XMPP::Error::IQ object if the request resulted in an error.

Please note that the contact you are given in that callback might not yet be on the roster (is_on_roster still returns a false value), if the server did send the roster push after the iq result of the roster set, so don't rely on the fact that the contact is on the roster.

delete_contact ($jid, $cb)

This method will send a request to the server to delete this contact from the roster. It will result in cancelling all subscriptions.

$cb will be called when the request was finished. The first argument to the callback might be a AnyEvent::XMPP::Error::IQ object if the request resulted in an error.

get_contact ($jid)

Returns the contact on the roster with the JID $jid. (If $jid is not bare the resource part will be stripped before searching)

NOTE: This method will also return contacts that we have only presence for. To be sure the contact is on the users roster you need to call the is_on_roster method on the contact.

The return value is an instance of AnyEvent::XMPP::IM::Contact.

get_contacts

Returns the contacts that are on this roster as AnyEvent::XMPP::IM::Contact objects.

NOTE: This method only returns the contacts that have a roster item. If you haven't retrieved the roster yet the presence information is still stored but you have to get the contacts without a roster item with the get_contacts_off_roster method. See below.

get_contacts_off_roster

Returns the contacts that are not on the roster but for which we have received presence. Return value is a list of AnyEvent::XMPP::IM::Contact objects.

See also documentation of get_contacts method of AnyEvent::XMPP::IM::Roster above.

get_own_contact

This method returns a AnyEvent::XMPP::IM::Contact object which stands for ourself. It will be used to keep track of our own presences.

debug_dump

This prints the roster and all it's contacts and their presences.
