Interface BearerControlListener

public interface BearerControlListener

The BearerControlListener interface defines the capabilities for receiving bearer (e.g. GPRS/EDGE or CSD) state information. When the user wants to receive these state events, an implementation class for the BearerControlListener interface must be created first.
The StateChanged method of this class must contain the processing code for different bearer states. This code shall leave the listener context as soon as possible (i.e. running a new thread). While the callback method does not return it cannot be called again if changes occur.
After creating an instance of the BearerControlListener class, this class instance has to be passed as a parameter to the BearerControl.addListener method. After that, the callback methods will be called by the runtime system each time the state changes occur.
