MovingAverage(CompositeEntity container,
java.lang.String name)
Construct an actor with the given container and name.
|
| Modifier and Type | Method and Description |
|---|---|
protected void |
_reinitialize()
Reinitialize local variables in response to changes in attributes.
|
void |
attributeChanged(Attribute attribute)
Set a flag that causes recalculation of various local variables
that are used in execution on the next invocation of fire().
|
void |
fire()
Consume the inputs and produce the output.
|
void |
initialize()
Perform domain-specific initialization by calling the
initialize(Actor) method of the director.
|
boolean |
prefire()
Return false if the input does not have a token.
