class Loop from Partition

	---Purpose: Builds the loops from a set of edges on a face.

uses

    Face                      from TopoDS,
    Edge                      from TopoDS,
    ListOfShape               from TopTools,
    DataMapOfShapeListOfShape from TopTools

is

    Create;
    
    Init (me : in out; F : Face from TopoDS)
	---Purpose: Init with <F> the set of edges must have
	--          pcurves on <F>. 
    is static;
    
    AddEdge (me : in out; E  : in out Edge from TopoDS;
    	    	    	  LV : ListOfShape from TopTools)
    	---Purpose: Add E with <LV>. <E> will be copied and trim 
    	--          by vertices in <LV>.
    is static;
    
    AddConstEdge  (me : in out; E : Edge from TopoDS)
	---Purpose: Add <E> as const edge, E can be in the result.
    is static;

    Perform(me : in out)
	---Purpose: Make loops.
    is static;
    
    NewWires (me)	
	---Purpose: Returns the list of wires performed. 
	--          can be an empty list.
	---C++: return const &
    returns ListOfShape from TopTools;
    	
    WiresToFaces (me : in out)
    	---Purpose:  Build faces from the wires result.
    is static;
    
    NewFaces (me)
        ---Purpose: Returns the list of faces.
    	---Warning: The method <WiresToFaces> as to be called before.
    	--          can be an empty list.
	---C++: return const &
    returns ListOfShape from TopTools;
