12.1.3.3Registering a Listener with an ATCommand Instance
After creating an instance of the ATCommandListener class, it must be passed as a parameter to the ATCommand.addListener() method. The callback methods of the instance will be called by the runtime system each time the corresponding events (URCs or signal state changes) occur on the corresponding device AT parser.
/* we have two ATCommands instances, atc1 and atc2 */ ATListenerA reminder_listener = new ATListenerA(); ATListenerB card_listener = new ATListenerB();
atc1.addListener(reminder_listener); atc2.addListener(card_listener);
The ATCommand.removeListener() method removes a listener object that has been previously added to the internal list table of listener objects. After it has been removed from the list it will not be called when URCs occur. If it was not previously registered the list remains unchanged.
The same ATCommandListener may be added to several ATCommand instances and several ATCommandListeners may be added to the same ATCommand.
