AnyEvent::XMPP::IM::Roster - Instant messaging roster for XMPP
my $con = AnyEvent::XMPP::IM::Connection->new (...);

$c->make_message ()->add_body ("Hello there!")->send;
}
This module represents a class for roster objects which contain contact
information.
It manages the roster of a JID connected by an
AnyEvent::XMPP::IM::Connection. It manages also the presence information
that is received.
You get the roster by calling the
"roster" method on an
AnyEvent::XMPP::IM::Connection object. There is no other way.
- is_retrieved
- Returns true if this roster was fetched from the server or false if this
roster hasn't been retrieved yet.
- new_contact ($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.
