Package ptolemy.vergil.actor

Class ClassDefinitionController

  • All Implemented Interfaces:
    NodeController
    public class ClassDefinitionController
extends ActorController
    This class provides interaction with nodes that represent Ptolemy II classes. This extends the base class by providing mechanisms in the context menu for creating an instance, creating a subclass, and converting to an instance.

    NOTE: There should be only one instance of this class associated with a given GraphController. This is because this controller listens for changes to the graph and re-renders the ports of any actor instance in the graph when the graph changes. If there is more than one instance, this rendering will be done twice, which can result in bugs like port labels appearing twice.
