Method Detail

isEmpty

boolean isEmpty()

Returns true if this shape encloses no area.

contains

boolean contains(float x,
                 float y)

Returns true if this shape contains the specified point.

contains

boolean contains(XY point)

Returns true if this shape contains the supplied point.

contains

boolean contains(float x,
                 float y,
                 float width,
                 float height)

Returns true if this shape completely contains the specified rectangle.

contains

boolean contains(IRectangle r)

Returns true if this shape completely contains the supplied rectangle.

intersects

boolean intersects(float x,
                   float y,
                   float width,
                   float height)

Returns true if this shape intersects the specified rectangle.

intersects

boolean intersects(IRectangle r)

Returns true if this shape intersects the supplied rectangle.

bounds

Rectangle bounds()

Returns a copy of the bounding rectangle for this shape.

bounds

Rectangle bounds(Rectangle target)

Initializes the supplied rectangle with this shape's bounding rectangle.

Returns:

the supplied rectangle.

pathIterator

PathIterator pathIterator(Transform at)

Returns an iterator over the path described by this shape.

Parameters:

at - if supplied, the points in the path are transformed using this.

pathIterator

PathIterator pathIterator(Transform at,
                          float flatness)

Returns an iterator over the path described by this shape.

Parameters:

at - if supplied, the points in the path are transformed using this.

flatness - when approximating curved segments with lines, this controls the maximum distance the lines are allowed to deviate from the approximated curve, thus a higher flatness value generally allows for a path with fewer segments.
