Class NonBlockingFire

java.lang.Object

ptolemy.domains.metroII.kernel.FireMachine

ptolemy.domains.metroII.kernel.NonBlockingFire

All Implemented Interfaces:

StartOrResumable

public class NonBlockingFire
extends FireMachine

NonBlockingFire is a wrapper for Ptolemy actor. It provides an implementation of FireMachine. More specifically, the wrapper implements a startOrResume() function that associates the state of FireMachine with the state of fire() of the wrapped actor as follows:

1. START: initial state
2. FINAL: final state

When startOrResume() is called, if the current state is START, the wrapper calls fire() of the wrapped actor, and transition to FINAL

Ptolemy II 11.0
