Net::XMPP2::Client - A XMPP Client abstraction |

=head1 SYNOPSIS |
| 31 |
|
| 32 |
use Net::XMPP2::Client; |
| 33 |
use AnyEvent; |
| 34 |
|
| 35 |
my $j = AnyEvent->condvar; |

=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. |

=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. |

| 155 |
|
| 156 |
Sends a message to the destination C<$dest_jid>. |
| 157 |
C<$msg> can either be a string or a L<Net::XMPP2::IM::Message> object. |
| 158 |
If C<$msg> is such an object C<$dest_jid> is optional, and will, when |
| 159 |
passed, override the destination of the message. |
| 160 |
|
| 161 |
C<$src> is optional. It specifies which account to use |
| 162 |
to send the message. If it is not passed L<Net::XMPP2::Client> will try |
| 163 |
to find an account itself. First it will look through all rosters |
| 164 |
to find C<$dest_jid> and if none found it will pick any of the accounts that |
| 165 |
are connected. |
| 166 |
|
| 167 |
C<$src> can either be a JID or a L<Net::XMPP2::IM::Account> object as returned |
| 168 |
by C<add_account> and C<get_account>. |
