All Implemented Interfaces:

java.lang.Runnable, Debuggable

public class ActiveActorManager
extends PtolemyThread

An active actor manager iterates an active actor until its postfire() returns false, or the director is requested to stop. If the active actor has pull input and its prefire() returns false, the actor manager will notify the CI director to process the pull request by the actor. When the actor has a period parameter, the actor manager will sleep between successive iterations of the actor for the duration given by the parameter, in milliseconds. This is used to control the execution rate of active actors that are always ready to produce the next output or request the next input.
