Constructor Detail

Ellipse2D

public Ellipse2D(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

_createFigure

protected BasicFigure _createFigure()
                             throws IllegalActionException

Implement the base class to create a rectangular shape.

Specified by:

_createFigure in class RectangularFigure2D

Returns:

A new Figure.

Throws:

IllegalActionException - If a parameter value is not valid.

_updateFigure

protected void _updateFigure()
                      throws IllegalActionException

Update the figure's position and size when the user changes the appropriate parameters.

Specified by:

_updateFigure in class RectangularFigure2D

Throws:

IllegalActionException - If a parameter value is not valid.
