public class Pause
extends Sink

An actor that pauses execution of a model when it receives a true token on any input channel. This is accomplished by calling pause() on the manager.

Field Detail

_hideName

public SingletonParameter _hideName

The parameter that hides the name of the actor. The default value is true.

Constructor Detail

Pause

public Pause(CompositeEntity container,
             java.lang.String name)
      throws IllegalActionException,
             NameDuplicationException

Construct an actor in the specified container with the specified name.

Parameters:

container - The container.

name - The name of this actor within the container.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the name coincides with an actor already in the container.

Method Detail

postfire

public boolean postfire()
                 throws IllegalActionException

Read one token from each input channel that has a token, and if any token is true, call pause() on the manager. If nothing at all is connected to the input port, then do nothing.

Specified by:

postfire in interface Executable

Overrides:

postfire in class AtomicActor<TypedIOPort>

Returns:

False if this actor is trying to pause execution if any token is true or if the input is not connected. If this actor is not trying to pause execution, then return the value returned by super.postfire().

Throws:

IllegalActionException - If there is no director or if there is no manager, or if the container is not a CompositeActor.
