public class Transformer
extends TypedAtomicActor

This is an abstract base class for actors that transform an input stream into an output stream. It provides an input and an output port, and manages the cloning of these ports.

Field Detail

input

public TypedIOPort input

The input port. This base class imposes no type constraints except that the type of the input cannot be greater than the type of the output.

output

public TypedIOPort output

The output port. By default, the type of this output is constrained to be at least that of the input.

Constructor Detail

Transformer

public Transformer(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.
