=head1 NAME

Net::MQTT::Message::ConnAck - Perl module to represent an MQTT ConnAck message

=head1 VERSION

version 1.142010

=head1 SYNOPSIS

  # instantiated by Net::MQTT::Message

=head1 DESCRIPTION

This module encapsulates a single MQTT Connection Acknowledgement
message.  It is a specific subclass used by L<Net::MQTT::Message>
and should not need to be instantiated directly.

=head1 METHODS

=head2 C<connack_reserved()>

Returns the reserved field of the MQTT Connection Acknowledgement
message.

=head2 C<return_code()>

Returns the return code field of the MQTT Connection Acknowledgement
message.  The module L<Net::MQTT::Constants> provides a function,
C<connect_return_code_string>, that can be used to convert this value
to a human readable string.
