=head2 onIncomingBroadcast

Called when D-Bus signal I<IncomingBroadcast> is received.

Generates event C<ON_INCOMING_BROADCAST> with arguments C<< $text, $topic >>.

}

=head2 onEmergencyBroadcast

Called when D-Bus signal I<EmergencyBroadcast> is received.

Generates event C<ON_EMERGENCY_BROADCAST> with arguments C<< $text, $topic >>.

=cut

sub onEmergencyBroadcast
{
    my ( $self, $text, $topic ) = @_;
    $self->trigger_event( "ON_EMERGENCY_BROADCAST", [ $text, $topic ] );

=head1 ACKNOWLEDGEMENTS

At first the guys from the oFono-Team shall be named: Marcel Holtmann and
Denis Kenzior, the maintainers and all the people named in ofono/AUTHORS.
Without their effort, there would no need for a Net::Radio::oFono module.

Further, Peter "ribasushi" Rabbitson helped a lot by providing hints
and support how to make this API accessor a valuable CPAN module.
