=head2 METHODS
=over 4
=item B<xml_node ()>
Returns the L<AnyEvent::XMPP::Node> object for this Stanza error.
This method returns undef if the Stanza timeouted.
In the case of a timeout the C<condition> method returns C<client-timeout>,
C<type> returns 'cancel' and C<code> undef.
=cut
sub xml_node {
$_[0]->{node}
}
=item B<type ()>
This method returns one of:
'cancel', 'continue', 'modify', 'auth' and 'wait'
=cut
sub type { $_[0]->{error_type} }
=item B<code ()>
This method returns the error code if one was found.
=cut
sub code { $_[0]->{error_code} }
=item B<condition ()>
Returns the error condition string if one was found when receiving the Stanza error.
It can be undef or one of:
bad-request
conflict
feature-not-implemented
forbidden
gone
internal-server-error
item-not-found
jid-malformed
not-acceptable
not-allowed
not-authorized
payment-required
recipient-unavailable
redirect
registration-required
remote-server-not-found
remote-server-timeout
resource-constraint
service-unavailable
subscription-required
undefined-condition
unexpected-request
=cut
sub condition { $_[0]->{error_cond} }
=item B<condition_node ()>
Returns the error condition node if one was found when receiving the Stanza error.
This is mostly for debugging purposes.
=cut
sub condition_node { $_[0]->{error_cond_node} }
=item B<text ()>
The humand readable error portion. Might be undef if none was received.
=cut
sub text { $_[0]->{error_text} }
sub string {
my ($self) = @_;
sprintf "stanza error: %s/%s (type %s): %s",
