p
- is the plane to assess for intersection with the shape's edges or
bounding curves.notablePoints
- represents the intersections of the plane with the supplied
bounds. These are used to disambiguate when two planes are identical and it needs
to be determined whether any points exist that fulfill all the bounds.bounds
- are a set of bounds that define an area that an
intersection must be within in order to qualify (provided by a GeoArea).public Bounds getBounds(Bounds bounds)

bounds
- is the optional input bounds object. If this is null,
a bounds object will be created. Otherwise, the input object will be modified.Copyright © 2000-2015 Apache Software Foundation. All Rights Reserved.
