|
|
|
|

|
|
|
|
# instantiated by Net::MQTT::Message
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This module encapsulates a single MQTT Subscribe message. It is a
|
|
specific subclass used by L<Net::MQTT::Message> and should not
|
|
need to be instantiated directly.
|
|
|
|
=head1 METHODS
|
|
|
|

|
|
|
|
Returns the message id field of the MQTT Subscribe message.
|
|
|
|
=head2 C<topics()>
|
|
|
|
Returns the list of topics of the MQTT Subscribe message. Each
|
|
element of the list is a 2-ple containing the topic and its associated
|
|
requested QoS level.
