Field Detail

xTranslate

public TypedIOPort xTranslate

The amount of translation in the x-axis during firing. If this transform is in accumulate mode, the translation value is accumulated for each firing.

yTranslate

public TypedIOPort yTranslate

The amount of translation in the y-axis during firing. If this transform is in accumulate mode, the translation value is accumulated for each firing.

initialXTranslation

public Parameter initialXTranslation

The initial translation in the x-axis This parameter should contain a DoubleToken. The default value of this parameter is 0.0.

initialYTranslation

public Parameter initialYTranslation

The initial translation in the y-axis This parameter should contain a DoubleToken. The default value of this parameter is 0.0.

Constructor Detail

Translate2D

public Translate2D(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

_applyInitialTransform

protected void _applyInitialTransform(Figure figure)
                               throws IllegalActionException

Set the initial transform of the given figure. This method is invoked by this base class during the initialize() method. Derived classes should implement it to provide class-specific behavior.

Specified by:

_applyInitialTransform in class GRTransform2D

Parameters:

figure - The figure to transform.

Throws:

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

_applyTransform

protected void _applyTransform(Figure figure)
                        throws IllegalActionException

Consume input tokens, and transform the given figure according to the current state of the transform. This method is invoked by this base classes during the fire() method.

Specified by:

_applyTransform in class GRTransform2D

Parameters:

figure - The figure to transform.

Throws:

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