public class ExternalTransition
extends Transition

An external transition exits from its source state and enters its destination state even if the two are the same state. So in every case the transition:

• will execute the source state exit action
• will destroy the source state with all its attributes
• will execute its transition action
• will create a new instance of the destination state and will initialize its attributes
• will execute the destination state entry action
