Class GeometryMethodOperation

  • All Implemented Interfaces:
    GeometryOperation
    public class GeometryMethodOperation
extends java.lang.Object
implements GeometryOperation
    Invokes a named operation on a set of arguments, the first of which is a Geometry. This class provides operations which are the methods defined on the Geometry class. Other GeometryOperation classes can delegate to instances of this class to run standard Geometry methods.
    Version:
