Method Summary

Modifier and Type	Method	Description
default Shape	getShape()	Returns a Shape for this object at the default scale (1).
Shape	getShape(double scale)	Returns a scaled Shape for this object (default scale is 1).
static Pnt2d[]	getShapePoints(Shape shape)
default Shape[]	getShapes()
default Shape[]	getShapes(double scale)	Returns a fixed sequence of Shape items for drawing this object, which must contain at least one item.

Method Details

getShape

Shape getShape(double scale)

Returns a scaled Shape for this object (default scale is 1). Must be defined by implementing classes. The interpretation of the scale factor is left to the implementing class. For example, for Pnt2d it specifies the size of the marker (see Pnt2d.getShape(double).

Parameters:

scale - the scale of the shape

Returns:

a Shape instance

getShape

default Shape getShape()

Returns a Shape for this object at the default scale (1).

Returns:

a Shape instance

getShapes

default Shape[] getShapes(double scale)

Returns a fixed sequence of Shape items for drawing this object, which must contain at least one item. This is to produce graphic representations that are too complex for a single Shape item. The returned shapes may also be displayed with different strokes or colors.

By default, this method returns a single item which is the primary shape (obtained by getShape(double)). Implementing classes should override this method if more than one shape must be returned For example, a GeometricEllipse returns three shape items: (a) the ellipse curve, (b) the center mark, (c) the major axes (see GeometricEllipse.getShapes(double)).

Parameters:

scale - a scale factor (may be used or ignored)

Returns:

sequence of Shape items

getShapes

default Shape[] getShapes()

getShapePoints

static Pnt2d[] getShapePoints(Shape shape)
