public class DoubleFork
extends TypedAtomicActor

DoubleFork is a simple DDE actor with one input and two outputs. It has two multiport outputs - "output1" and "output2." The fire method of DoubleFork passes real tokens through the first output (output1). Real tokens are never produced on output2.

Constructor Detail

DoubleFork

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

Construct a DoubleFork actor with the specified container and name.

Parameters:

container - The TypedCompositeActor that contains this actor.

name - The name of this actor.

Throws:

NameDuplicationException - If the name of this actor duplicates that of a actor already contained by the container of this actor.

IllegalActionException - If there are errors in instantiating and specifying the type of this actor's ports.

Method Detail

fire

public void fire()
          throws IllegalActionException

Execute this actor by consuming a real input token and producing an equivalent real token on output1.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor

Throws:

IllegalActionException - If there are errors in obtaining the receivers of this actor.

postfire

public boolean postfire()
                 throws IllegalActionException

Return true if this actor will allow subsequent iterations to occur; return false otherwise.

Specified by:

postfire in interface Executable

Overrides:

postfire in class AtomicActor

Returns:

True if continued execution is enabled; false otherwise.

Throws:

IllegalActionException - Not thrown in this base class.
