is static;
IsVertex(me)
---Purpose: Returns Standard_True when the point coincide with
-- an existing vertex.
returns Boolean from Standard

NbPointOnRst(me)
---Purpose: Returns the number of arc containing the extremity.
-- If the method returns 0, the point is inside the
-- surface.
-- Otherwise, the extremity lies on at least 1 arc,
-- and all the information (arc, parameter, transitions)
-- are given by the point on restriction (PointOnRst)
-- returned by the next method.
returns Integer from Standard
