Provides metadata about the function. author:    Martin Davis version:    1.0 Constructor Summary public   GeometryFunction(String name, int nArgs, int nParams)      public   GeometryFunction(String name, int nArgs, int nParams, String description)      Method Summary abstract public  Geometry execute(Geometry[] geom, double[] param)      Exectute the function on the geometry(s) in the geom array. The function can expect that the correct number of geometry arguments is present in the array. Integer parameters must be passed as doubles. If no result can be computed for some reason, null should be returned to indicate this to the caller. Exceptions may be thrown and must be handled by the caller. Parameters:   geom - the geometry arguments Parameters:   param - any non-geometric arguments. public  String getDescription()      public static  GeometryFunction getFunction(String name)      public static  GeometryFunction getFunction(Collection functions, String name)      public static  GeometryFunction[] getFunctions()      public  int getGeometryArgumentCount()      public  String getName()      public static  List getNames()      public static  List getNames(Collection functions)      public  int getParameterCount()      public  String toString()      Constructor Detail GeometryFunction public GeometryFunction(String name, int nArgs, int nParams)(Code) GeometryFunction public GeometryFunction(String name, int nArgs, int nParams, String description)(Code) Method Detail execute abstract public Geometry execute(Geometry[] geom, double[] param)(Code) Exectute the function on the geometry(s) in the geom array.
