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.
