deferred class Interference from Intf

	---Purpose: Describes the   Interference  computation    result
	--          between polygon2d or polygon3d or polyhedron.

uses    SectionPoint      from Intf,
    	SeqOfSectionPoint from Intf,
    	SectionLine       from Intf,
    	SeqOfSectionLine  from Intf,
    	TangentZone       from Intf,
    	SeqOfTangentZone  from Intf


raises  OutOfRange from Standard


is  Initialize(Self : Boolean from Standard);

    SelfInterference(me   : in out;
    	    	     Self : Boolean from Standard) is protected;
    ---Purpose: Only one argument for the intersection.

    NbSectionPoints(me)
    	    	    returns Integer is static;
    ---Purpose: Gives the number   of  points of  intersection  in the
    --          interference.

    PntValue       (me;
    	    	    Index      : in Integer)
		    returns SectionPoint from Intf
    	    	    raises OutOfRange from Standard
    	    	    is static;
    ---Purpose: Gives the point of  intersection of address  Index in
    --          the interference.
    --
    ---C++: return const &


    NbSectionLines (me)
    	    	    returns Integer is static;
    ---Purpose: Gives the number  of polylines of  intersection in the
    --          interference.

    LineValue      (me;
    	    	    Index      : in Integer)
    	    	    returns SectionLine from Intf
    	    	    raises OutOfRange from Standard
    	    	    is static;
    ---Purpose: Gives the polyline of intersection at address <Index> in
    --          the interference.
    --
    ---C++: return const &



    NbTangentZones  (me)
    	    	    returns Integer is static;
    ---Purpose: Gives the number of zones of tangence in the interference.

    ZoneValue      (me;
    	    	    Index      : in Integer)
    	    	    returns TangentZone from Intf
    	    	    raises OutOfRange from Standard
    	    	    is static;
    ---Purpose: Gives  the zone of  tangence at address   Index in the
    --          interference.
    --
    ---C++: return const &


    GetTolerance   (me)
    	    	    returns Real
    	    	    is static;
    ---Purpose: Gives the tolerance used for the calculation.

     	    	    ThePnt : in SectionPoint from Intf)
		    returns Boolean
    	    	    is static;
    ---Purpose: Tests if the polylines of  intersection or the zones of
    --          tangence contain the point of intersection <ThePnt>.


    Insert         (me         : in out;
     	    	    TheZone    : in TangentZone from Intf)
		    returns Boolean
    	    	    is static;
    ---Purpose: Inserts a new zone of tangence in  the current list of
    --          tangent zones of  the interference  and  returns  True
    --          when done.


    Insert         (me         : in out;
     	    	    pdeb       : in SectionPoint from Intf;
     	    	    pfin       : in SectionPoint from Intf)
    	    	    is static;
    ---Purpose: Insert a new segment of intersection in the current  list of
    --          polylines of intersection of the interference.
