Interface StateMachineEventListener

All Superinterfaces:

java.util.EventListener

All Known Implementing Classes:

StateMachineEventAdapter

public interface StateMachineEventListener
extends java.util.EventListener

The listener interface for receiving "interesting" state machine events:

• the state machine is reset,
• the state machine is resumed,
• the state machine is suspended,
• the state machine fires a transition changing the current state,
• the state machine fires a transition making it loop on the current state.

The class that is interested in processing a state machine event either implements this interface (and all the methods it contains) or extends the abstract StateMachineEventAdapter class (overriding only the methods of interest).

The listener object created from that class is then registered with a state machine using the state machine's addStateMachineListener method. When the state machine is resumed, reset, suspended, goes to another state or loops on the current state, the relevant method in the listener object is invoked and the StateMachineEvent is passed to it.
