Field Detail

A

public TypedIOPort A

Input for tokens to be inverted. This is a multiport of fix point type

Constructor Detail

LogicalNot

public LogicalNot(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

fire

public void fire()
          throws IllegalActionException

Output the fixpoint value of the sum of the input bits. If there is no inputs, then produce null.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If there is no director.

isStrict

public boolean isStrict()

Return false. This actor can produce some output event the input receiver has status unknown.

Specified by:

isStrict in interface Executable

Overrides:

isStrict in class SynchronousFixTransformer

Returns:

False.

preinitialize

public void preinitialize()
                   throws IllegalActionException

Override the base class to declare that the A and port does not depend on the output in a firing.

Specified by:

preinitialize in interface Initializable

Overrides:

preinitialize in class SynchronousFixTransformer

Throws:

IllegalActionException - Not thrown in this base class.
