28 Net::XMPP2::Client - A XMPP Client abstraction
29
30 =head1 SYNOPSIS
31
32 use Net::XMPP2::Client;
33 use AnyEvent;
34
35 my $j = AnyEvent->condvar;
36
37 my $cl = Net::XMPP2::Client->new;

41
42 =head1 DESCRIPTION
43
44 This module tries to implement a straight forward and easy to
45 use API to communicate with XMPP entities. L<Net::XMPP2::Client>
46 handles connections and timeouts and all such stuff for you.
47
48 For more flexibility please have a look at L<Net::XMPP2::Connection>
49 and L<Net::XMPP2::IM::Connection>, they allow you to control what
50 and how something is being sent more precisely.

72 =head2 add_account ($jid, $password, $host, $port)
73
74 This method adds a jabber account for connection with the JID C<$jid>
75 and the password C<$password>.
76
77 C<$host> and C<$port> are optional and can be undef. C<$host> overrides the
78 host to connect to.
79
80 Returns 1 on success and undef when the account already exists.

203
204 Sends a message to the destination C<$dest_jid>.
205 C<$msg> can either be a string or a L<Net::XMPP2::IM::Message> object.
206 If C<$msg> is such an object C<$dest_jid> is optional, and will, when
207 passed, override the destination of the message.
208
209 C<$src> is optional. It specifies which account to use
210 to send the message. If it is not passed L<Net::XMPP2::Client> will try
211 to find an account itself. First it will look through all rosters
212 to find C<$dest_jid> and if none found it will pick any of the accounts that
213 are connected.
214
215 C<$src> can either be a JID or a L<Net::XMPP2::IM::Account> object as returned
216 by C<add_account> and C<get_account>.

289
290 This method tries to find any account that has the contact C<$jid>
291 on his roster. If no account with C<$jid> on his roster was found
292 it takes the first one that is connected. (Return value is a L<Net::XMPP2::IM::Account>
293 object).

318 =head2 get_contacts_for_jid ($jid)

322 that we are connected to.

338
339 This method returns the presence for the contact C<$jid> with the highest
340 priority.
341
342 If the contact C<$jid> is on multiple account's rosters it's undefined which
343 roster the presence belongs to.

365 =head2 set_presence ($show, $status, $priority)
366
367 This sets the presence of all accounts. For a meaning of C<$show>, C<$status>
368 and C<$priority> see the description of the C<%attrs> hash in
369 C<send_presence> method of L<Net::XMPP2::Writer>.

387 =head1 EVENTS
388
389 In the following event descriptions the argument C<$account>
390 is always a L<Net::XMPP2::IM::Account> object.
391
392 All events from L<Net::XMPP2::IM::Connection> are forwarded to the client,
393 only that the first argument for every event is a C<$account> object.
394
395 Aside fom those, these events can be registered on with C<reg_cb>:
396
397 =over 4
398
399 =item connected => $account
400
401 This event is sent when the C<$account> was successfully connected.
402
403 =item connect_error => $account
404
405 This event is emitted when an error occured in the connection process for the
406 account C<$account>.
407
408 =item error => $account
409
410 This event is emitted when any error occured while communicating
411 over the connection to the C<$account> - after a connection was established.
