java.lang.Object |
clone(Workspace workspace)
Clone the actor into the specified workspace.

void |
connectionsChanged(Port port)
Pre-calculate the rates to be set in the rate parameter of the
input port.
|
void |
fire()
Fire the actor once.
|
void |
initialize()
Initialize this actor and rate parameters so that it will read
from the control port in the first iteration.
|
boolean |
postfire()
Update rate parameters for the next iteration.
|
boolean |
prefire()
Return false if the port or channel it needs to read from in the
following firing does not have a token.
