<!-- Before adding ANYTHING in here, please start a discussion on the dev list.
|
||||||
|
Ideally the Axis2 build should only use Maven central (which is available
|
||||||
|
by default) and nothing else. We had troubles with other repositories in
|
||||||
|
the past. Therefore configuring additional repositories here should be
|
||||||
|
considered very carefully. -->

|
* interface methods are intended to be implemented by the concrete class that extends this abstract class and

|
* via HTTP Protocol).
|

|

|
* This class contains the Device-Management specific implementation for all the MQTT functionality. This includes

|
* connecting to a MQTT Broker & subscribing to the appropriate MQTT-topic, action plan upon losing connection or
|

|
* successfully delivering a message to the broker and processing incoming messages. Makes use of the 'Paho-MQTT'
