AnyEvent::XMPP::IM::Contact - Instant messaging roster contact
my $con = AnyEvent::XMPP::IM::Connection->new (...);
...
my $ro = $con->roster;
if (my $c = $ro->get_contact ('test@example.com')) {
$c->make_message ()->add_body ("Hello there!")->send;
}
This module represents a class for contact objects which populate a roster
(AnyEvent::XMPP::IM::Roster.
There are two types of 'contacts' that are managed by this class.
The first are contacts that are on the users roster, and the second are
contacts that are not on the users roster.
To find our whether this is a contact which is actually available
as roster item in the users roster, you should consult the
"is_on_roster" method (see below).
Another special kind of contact is the contact which stands for
ourself and is mostly only used for keeping track of our own presences and
resources. But note that even if the
"is_me" method returns true, the
"is_on_roster" method might also return a
true value, in case we have a roster item of ourself on the roster (which
might happen in rare cases :).
You can get an instance of this class only by calling the
"get_contact" function on a roster
object.
- send_update ($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.
$presence must be a AnyEvent::XMPP::Node object
and should be a presence packet.
- get_presence ($jid)
- 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.
- get_presences
- Returns all presences of this contact in form of
AnyEvent::XMPP::IM::Presence objects.
- get_priority_presence
- Returns the presence with the highest priority.
- groups
- Returns the list of groups (strings) this contact is in.
- jid
- Returns the bare JID of this contact.
- name
- Returns the (nick)name of this contact.
- is_on_roster ()
- Returns 1 if this is a contact that is officially on the roster and not
just a contact we've received presence information for.
- is_me
- Returns a true value when this contacts stands for ourself and is only
used for receiving presences of our own resources.
- subscription
- Returns the subscription state of this contact, which can be one of:
'none', 'to', 'from', 'both'
If the contact isn't on the roster anymore this method
returns:
'remove'
- ask
- Returns 'subscribe' if we asked this contact for subscription.
- subscription_pending
- Returns true if this contact has a pending subscription. That means: the
contact has to aknowledge the subscription.
- nickname
- Returns the nickname of this contact (or, if none is set in the roster, it
returns the node part of the JID)
- make_message (%args)
- This method returns a AnyEvent::XMPP::IM::Message object with the to field
set to this contacts JID.
%args are further arguments for the
message constructor.
