public abstract class GRTransform
extends GRActor3D

An abstract base class for a transform operator of GR shapes. This actor will only have meaning in the GR domain. The parameter accumulate determines whether transformations are accumulated or reset during firing.

Field Detail

accumulate

public Parameter accumulate

Boolean value determining whether transformations are accumulated or reset for each firing.

sceneGraphIn

public TypedIOPort sceneGraphIn

The input port for connecting to other GR Actors in the scene graph.

sceneGraphOut

public TypedIOPort sceneGraphOut

The output port for connecting to other GR Actors in the scene graph.

Constructor Detail

GRTransform

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

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

initialize

public void initialize()
                throws IllegalActionException

Setup the transform object.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class GRActor

Throws:

IllegalActionException - If the current director is not a GRDirector.

_isAccumulating

protected boolean _isAccumulating()
                           throws IllegalActionException

Return the value of the accumulate parameter.

Returns:

the accumulation mode

Throws:

IllegalActionException - If the value of some parameters can't be obtained

_makeSceneGraphConnection

protected void _makeSceneGraphConnection()
                                  throws IllegalActionException

Description copied from class: GRActor

Setup the scene graph connections of this actor. Derived GR Actors should override this method.

Specified by:

_makeSceneGraphConnection in class GRActor

Throws:

IllegalActionException - Always thrown for this base class.
