class Interference from TopOpeBRepDS inherits TShared from MMgt

	---Purpose: An interference    is   the   description  of  the
	--          attachment of  a new  geometry on a  geometry. For
	--          example an intersection point  on an Edge or on  a
	--          Curve.
	--          
	--          The Interference contains the following data :
	--          
	--          - Transition :  How the interference  separates the
	--          existing geometry in INSIDE and OUTSIDE.
	--          
	--          - SupportType : Type of  the object supporting the
	--          interference. (FACE, EDGE, VERTEX, SURFACE, CURVE).
	--          
	--          - Support :  Index  in the data  structure  of the
	--          object supporting the interference.
	--          
	--          - GeometryType  :   Type  of the  geometry of  the
	--          interference (SURFACE, CURVE, POINT).
	--          
	--          - Geometry : Index  in the data structure  of the
	--          geometry.
