private class MeshElementIDFactory from SMDS inherits MeshIDFactory

	---Purpose: 

uses
    DataMapOfIntegerMeshElement from SMDS,
    MeshElement from SMDS

is

    Create returns mutable MeshElementIDFactory from SMDS;

    GetFreeID(me:mutable) returns Integer is redefined static;
    	---Purpose: returns a free identifier for mesh from
    	--          the pool of ID
        ---C++: inline
	
    ReleaseID(me: mutable;ID :Integer) is redefined static;
    	---Purpose: free the ID and give it back to the pool of ID
        ---C++: inline

    BindID(me: mutable;ID :Integer; elem : MeshElement from SMDS )
    returns Boolean;
    	---Purpose: bind the ID with the mesh element
    	--          returns False if the ID is already bound.
    	--          In this case the element is not replaced
        ---C++: inline

    MeshElement(me;ID :Integer) returns MeshElement from SMDS;
    	---Purpose: returns the MeshElement associated with ID
    	--          raises an exception if the ID is not bound
        ---C++: inline
