Package org.springframework.statemachine.support

Class StateMachineObjectSupport.StateMachineListenerRelay

java.lang.Object

org.springframework.statemachine.support.StateMachineObjectSupport.StateMachineListenerRelay

All Implemented Interfaces:

StateMachineListener<S,E>

Enclosing class:

StateMachineObjectSupport<S,E>

protected class StateMachineObjectSupport.StateMachineListenerRelay
extends Object
implements StateMachineListener<S,E>

This class is used to relay listener events from a submachines which works as its own listener context. User only connects to main root machine and expects to get events for all machines from there.
