Class MethodSelfTransition

java.lang.Object

org.apache.mina.statemachine.transition.AbstractSelfTransition

org.apache.mina.statemachine.transition.MethodSelfTransition

All Implemented Interfaces:

SelfTransition

public class MethodSelfTransition
extends AbstractSelfTransition

SelfTransition which invokes a Method. The Method can have zero or any number of StateContext and State regarding order

Normally you wouldn't create instances of this class directly but rather use the SelfTransition annotation to define the methods which should be used as transitions in your state machine and then let org.apache.mina.statemachine#StateMachineFactory create a StateMachine for you.
