Class StateMachine.State.Event

java.lang.Object
  sm.StateMachine.State.Transition
      sm.StateMachine.State.Event

Enclosing class:

StateMachine.State

public class StateMachine.State.Event

extends StateMachine.State.Transition

A transition triggered in the canvas. The Event class can be directly used or extended to define specific event. The above example shows how a state machine, sm1, can receive "longPress" events provided by another state machine, sm2.

 StateMachine sm1, sm2;
 ...
 sm1 = new StateMachine("sm1", c) {

			public State start = new State("start") {
				public Transition event = new Event("longPress") {
					public void action() {
						System.out.println("a long press event");
				}
	        };
		};
 };

 sm2 = new StateMachine("sm2", c) {
 	
 	public State start = new State("start") {
		public Transition press = new Press(BUTTON1, ">> wait") {
			public void action() {
				armTimer(1000);
			}
		};
	};
	
	public State wait = new State("wait") {
		public Transition release = new Release(BUTTON1, ">> start") {
			public void action() {
				disarmTimer();
			}
		};
		
		public Transition longPress = new TimeOut(">> start") {
			public void action() {
				sm1.processEvent(new SMVirtualEvent("longPress"));
			}
		};
	};
 };
