Class DataflowWithRates

java.lang.Object
 extended byptolemy.caltrop.ddi.AbstractDDI
 extended byptolemy.caltrop.ddi.Dataflow
 extended byptolemy.caltrop.ddi.DataflowWithRates

All Implemented Interfaces:: DDI, Executable

Direct Known Subclasses:: DDF, SDF

public class DataflowWithRates
extends Dataflow

A base class that provides support for dataflow models that publish external rate information. This includes SDF (where the rates are constant) and DDF (where the rates are published once an action is selected.
