Interface ConnectionListener

All Superinterfaces:

CallListener, java.util.EventListener

All Known Subinterfaces:

CallControlConnectionListener, CallControlTerminalConnectionListener, TerminalConnectionListener

public interface ConnectionListener

extends CallListener

This interface is an extension of the CallListener interface, and reports state changes both of the Call and its Connections.

Introduction

As is true for the CallListener interface, specific Connection object state changes are reported to specific corresponding ConnectionListener methods. The eventID carried by the event (a ConnectionEvent) corresponds to the method called, and indicates which specific state change occurred.

Adding a Listener to a Call

Applications may add a ConnectionListener to a Call via one of several mechanisms. They may directly add a ConnectionListener by implementing the ConnectionListener interface, and then invoking the Call.addCallListener method. Applications may also add ConnectionListener to Calls indirectly by implementing the ConnectionListener interface, and then invoking the Address.addCallListener and Terminal.addCallListener methods. These methods add the given listener to the Call when the Call comes to the Address or Terminal. See the specifications for Call, Address, and Terminal for more information.

Call State Changes and Connection Events

In the core package, an event is delivered whenever the Call changes state. An event is delivered to a method of this interface specifically when a Connection object changes state. The method called, and the event ID reported, indicate the new Call state. The methods in this interface are: connectionAlerting, connectionConnected, connectionDisconnected, connectionFailed, connectionInProgress, and connectionUnknown.

Connection Events

All events pertaining to the Connection object are reported on this interface. Connection events are instances of the ConnectionEvent interface, which in turn, extends the CallEvent event interface. In the core package, an event is delivered to this interface whenever a Connection changes state.
