SYNOPSIS
my $con = AnyEvent::XMPP::IM::Connection->new (...);
...
my $ro = $con->roster;
if (my $c = $ro->get_contact ('test@example.com')) {
$c->make_message ()->add_body ("Hello there!")->send;
}
DESCRIPTION
This module represents a class for contact objects which populate a
roster (AnyEvent::XMPP::IM::Roster.
There are two types of 'contacts' that are managed by this class. The
first are contacts that are on the users roster, and the second are
contacts that are not on the users roster.
To find our whether this is a contact which is actually available as
roster item in the users roster, you should consult the "is_on_roster"
method (see below).
Another special kind of contact is the contact which stands for ourself
and is mostly only used for keeping track of our own presences and
resources. But note that even if the "is_me" method returns true, the
"is_on_roster" method might also return a true value, in case we have a
roster item of ourself on the roster (which might happen in rare cases
:).
You can get an instance of this class only by calling the "get_contact"
function on a roster object.
METHODS
send_update ($cb, %upd)
This method updates a contact. If the request is finished it will
call $cb. If it resulted in an error the first argument of that
callback will be a AnyEvent::XMPP::Error::IQ object.
The %upd hash should have one of the following keys and defines
what parts of the contact to update:
name => $name
Updates the name of the contact. $name = '' erases the contact.
add_group => $groups
Adds the contact to the groups in the array reference $groups.
remove_group => $groups
Removes the contact from the groups in the array reference
$groups.
groups => $groups
This sets the groups of the contact. $groups should be an array
reference of the groups.
send_subscribe ()
This method sends this contact a subscription request.
send_subscribed ()
This method accepts a contact's subscription request.
send_unsubscribe ()
This method sends this contact a unsubscription request.
send_unsubscribed ()
This method sends this contact a unsubscription request which
unsubscribes ones own presence from him (he wont get any further
presence from us).
update ($item)
This method wants a AnyEvent::XMPP::Node in $item which should be a
roster item received from the server. The method will update the
contact accordingly and return it self.
update_presence ($presence)
This method updates the presence of contacts on the roster.
$presence must be a AnyEvent::XMPP::Node object and should be a
presence packet.

This method returns a presence of this contact if it is available.
The return value is an instance of AnyEvent::XMPP::IM::Presence or
undef if no such presence exists.

subscription_pending
Returns true if this contact has a pending subscription. That
means: the contact has to aknowledge the subscription.
