=head2 METHODS |
| 105 |
|
| 106 |
=head3 xml_node () |
| 107 |
|
| 108 |
Returns the L<Net::XMPP2::Node> object for this IQ error. |
| 109 |
This method returns undef if the IQ timeouted. |
| 110 |
|
| 111 |
In the case of a timeout the C<condition> method returns C<client-timeout>, |
| 112 |
C<type> returns 'cancel' and C<code> undef. |

=head3 |
| 121 |
|
| 122 |
=head3 type () |
