	---Purpose: Implementation some formal   
    	--          opereations with Set of shapes        

uses 
    Shape from TopoDS,
    MapOfOrientedShape from TopTools, 
    ListOfShape from TopTools,
    ShapeEnum from TopAbs 
    
--raises

is 
    Create 
    	---Purpose: Empty constructor
    	returns ShapeSet from GEOMAlgo; 

    Add(me:out; 
    	    theLS:ListOfShape from TopTools); 
    	---Purpose: Adds shapes from the list theLS to the Set   
	 
    Add(me:out; 
    	    theShape:Shape from TopoDS);
    	---Purpose: Adds shape theShape to the Set 
	
    Add(me:out; 
    	    theShape:Shape from TopoDS; 
    	    theType :ShapeEnum from TopAbs);  
    	---Purpose: Adds sub-shapes of shape theShape, 
    	--          that have type theType to the Set 
	 
    Subtract(me:out; 
	    theSet:ShapeSet from GEOMAlgo); 
    	---Purpose: Removes shapes of theSet from the Set 
	 
    Clear(me:out);
    	---Purpose: Clears internal fields 
	 
    Contains(me; 
	    theSet:ShapeSet from GEOMAlgo) 
    	---Purpose: Returns True if the Set contains  
    	--          all shapes of theSet 
    	returns Boolean from Standard; 
    		     
    GetSet(me) 
    	---Purpose: Returns the Set  
    	returns ListOfShape from TopTools; 
    ---C++: return const &

    IsEqual(me; 
	    theOther: ShapeSet from GEOMAlgo) 
    	---Purpose: Returns True if the Set==theSet 
    	returns Boolean from Standard;
