class IntersectionPoint from IntRes2d

    ---Purpose: Definition of an intersection point between two
    --          2D curves.


inherits Storable from Standard

uses Pnt2d      from gp,
     Transition from IntRes2d
is

    Create

	---Purpose: Empty constructor.

    	returns IntersectionPoint from IntRes2d;


    Create(P: Pnt2d from gp; Uc1,Uc2:Real from Standard;
           Trans1,Trans2: Transition from IntRes2d;
           ReversedFlag: Boolean from Standard)
	   
	---Purpose: Creates an IntersectionPoint.
	--          if ReversedFlag is False, the parameter Uc1(resp. Uc2)
	--          and the Transition Trans1 (resp. Trans2) refer to 
	--          the first curve (resp. second curve) otherwise Uc1 
	--          and Trans1 (resp. Uc2 and Trans2) refer to the 
	--          second curve (resp. the first curve).

      	---C++: inline	   

	returns IntersectionPoint from IntRes2d;
	

    SetValues(me:in out; P: Pnt2d from gp; Uc1,Uc2:Real from Standard;
              Trans1,Trans2: Transition from IntRes2d;
              ReversedFlag: Boolean from Standard)

	---Purpose: Sets the values for an existing intersection 
	--          point. The meaning of the parameters are the same 
	--          as for the Create.

	---C++: inline

	is static;



    Value(me)
    
    	---Purpose: Returns the value of the coordinates of the
    	--          intersection point in the 2D space.

	---C++: inline
	---C++: return const &

    	returns Pnt2d from gp
    	is static;


    ParamOnFirst(me)

    	---Purpose: Returns the parameter on the first curve.

	---C++: inline

    	returns Real from Standard
	is static;


    ParamOnSecond(me)

    	---Purpose: Returns the parameter on the second curve.

       	---C++: inline

    	returns Real from Standard
	is static;


    TransitionOfFirst(me)
    
    	---Purpose: Returns the transition of the 1st curve compared to
    	--          the 2nd one.

	---C++: inline
        ---C++: return const &
    	returns Transition from IntRes2d
	is static;


    TransitionOfSecond(me)
    
    	---Purpose: returns the transition of the 2nd curve compared to
    	--          the 1st one.

	---C++: inline
        ---C++: return const &
    	returns Transition from IntRes2d
