public class BooleanToAnything
extends Converter

This actor converts a boolean input token into any data type.

A true at the input results in an output with value given by the trueValue parameter. A false at the input results in an output with value given by the falseValue parameter.

Constructor Detail

BooleanToAnything

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

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

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

NameDuplicationException - If the container already has an actor with this name.

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the actor into the specified workspace. This calls the base class and then sets the value public variable in the new object to equal the cloned parameter in that new object.

Overrides:

clone in class AtomicActor

Parameters:

workspace - The workspace for the new object.

Returns:

A new actor.

Throws:

java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

fire

public void fire()
          throws IllegalActionException

Read exactly one token from the input and output the token given by either the falseValue or trueValue parameter.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor

Throws:

IllegalActionException - If there is no director.

prefire

public boolean prefire()
                throws IllegalActionException

Return false if the input port has no token, otherwise return what the superclass returns (presumably true).

Specified by:

prefire in interface Executable

Overrides:

prefire in class AtomicActor

Returns:

True if this actor is ready for firing, false otherwise.

Throws:

IllegalActionException - If there is no director.
