Field Detail

input

public TypedIOPort input

The input port. The type of this port is BaseType.STRING. This is a multiport.

output

public TypedIOPort output

The output port. The type of this port is BaseType.GENERAL. This is a multiport.

Constructor Detail

Memory

public Memory(CompositeEntity cont,
              java.lang.String name)
       throws IllegalActionException,
              NameDuplicationException

Construct a Memory actor with the specified container and name.

Parameters:

cont - The container of this actor.

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

Execute this actor indefinitely unless there is an error during one of the conditional rendezvous attempts.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If there is an error during communication via the ports.

getString

public java.lang.String getString()

Return the value of the string that is associated with the input token.

Returns:

The String value of the input token.
