public abstract class GRActor2D
extends GRActor

A base class for all two-dimensional GR actors. These actors use Diva to render two-dimensional scenes in the GR domain. This is an abstract class that is never used as a standalone actor in a Ptolemy model. Subclasses of this actor include Geometry actors, Transform actors, Interaction actors, and the ViewScreen2D display actor.

Since:

Ptolemy II 4.0

Constructor Detail

GRActor2D

public GRActor2D(CompositeEntity container,
                 java.lang.String name)
          throws IllegalActionException,
                 NameDuplicationException

Create a new GRActor in the specified container with the specified name. The name must be unique within the container or an exception is thrown. The container argument must not be null, or a NullPointerException will be thrown.

Parameters:

container - The container.

name - The name of this actor within the container.

Throws:

IllegalActionException - If this actor cannot be contained by the proposed container (see the setContainer() method).

NameDuplicationException - If the name coincides with an entity already in the container.

Method Detail

_setViewScreen

protected void _setViewScreen(GRActor actor)

Set the view screen that this actor is connected to.

Specified by:

_setViewScreen in class GRActor

Parameters:

actor - The actor.

Throws:

java.lang.RuntimeException - If the given actor is not a ViewScreen2D.
