Field Detail

increment

public MethodCallPort increment

The increment port. If this input port receives a token, then the counter is incremented. The port has type general.

decrement

public MethodCallPort decrement

The decrement port. If this input port receives a token, then the counter is decremented. The port has type general.

output

public MethodCallPort output

The output port with type IntToken.

Constructor Detail

Counter

public Counter(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

initialize

public void initialize()
                throws IllegalActionException

Reset the count of inputs to zero.

Specified by:

initialize in interface Component

Overrides:

initialize in class AtomicComponent

Throws:

IllegalActionException - If the parent class throws it.
