Class VoidShapeGeometry

java.lang.Object

com.yworks.yfiles.graph.styles.VoidShapeGeometry

All Implemented Interfaces:

IShapeGeometry

public final class VoidShapeGeometry
extends Object
implements IShapeGeometry

A void implementation of the IShapeGeometry interface that does nothing and behaves like an empty geometry.

This class implements the singleton pattern. Use the shared static INSTANCE of this class instead of null were null is not allowed. The VoidNodeStyleRenderer does so for example.

Field Detail

INSTANCE

public static final VoidShapeGeometry INSTANCE

The VoidShapeGeometry singleton.

Method Detail

getInstance

public static VoidShapeGeometry getInstance()

Returns the com.yworks.yfiles.common.drawing.VoidShapeGeometry singleton.

Returns:

the com.yworks.yfiles.common.drawing.VoidShapeGeometry singleton.

getIntersection

public final PointD getIntersection(PointD inner,
                                    PointD outer)

This implementation always returns null.

Specified by:

getIntersection in interface IShapeGeometry

Parameters:

inner - The first point of the line that is inside the shape.

outer - The second point of the line that is outside the shape.

Returns:

This implementation always returns null.

See Also:

IShapeGeometry.getIntersection(PointD, PointD)

getOutline

public final GeneralPath getOutline()

This implementation returns an empty path.

This means that the outline never intersects any line or contains any point.

Specified by:

getOutline in interface IShapeGeometry

Returns:

The empty path.

See Also:

IShapeGeometry.getOutline()

isInside

public final boolean isInside(PointD location)

This implementation always returns false.

Specified by:

isInside in interface IShapeGeometry

Parameters:

location - The point to test.

Returns:

false
