---Purpose: Returns Standard_True if the face <F> has been
-- modified. In this case, <S> is the new geometric
-- support of the face, <L> the new location, <Tol>
-- the new tolerance. Otherwise, returns
-- Standard_False, and <S>, <L>, <Tol> are not
-- significant.
NewCurve(me: mutable; E : Edge from TopoDS;

---Purpose: Returns Standard_True if the edge <E> has been
-- modified. In this case, <C> is the new geometric
-- support of the edge, <L> the new location, <Tol>
-- the new tolerance. Otherwise, returns
-- Standard_False, and <C>, <L>, <Tol> are not
-- significant.
NewPoint(me: mutable; V : Vertex from TopoDS;

returns Boolean from Standard;
---Purpose: Returns Standard_True if the vertex <V> has been
-- modified. In this case, <P> is the new geometric
-- support of the vertex, <Tol> the new tolerance.
-- Otherwise, returns Standard_False, and <P>, <Tol>
-- are not significant.

---Purpose: Returns Standard_True if the edge <E> has a new
-- curve on surface on the face <F>.In this case, <C>
-- is the new geometric support of the edge, <L> the
-- new location, <Tol> the new tolerance.
--
-- Otherwise, returns Standard_False, and <C>, <L>,
-- <Tol> are not significant.
--
-- <NewE> is the new edge created from <E>. <NewF>
-- is the new face created from <F>. They may be usefull.

returns Boolean from Standard;
---Purpose: Returns Standard_True if the Vertex <V> has a new
-- parameter on the edge <E>. In this case, <P> is
-- the parameter, <Tol> the new tolerance.
-- Otherwise, returns Standard_False, and <P>, <Tol>
-- are not significant.

---Purpose: Returns the continuity of <NewE> between <NewF1>
-- and <NewF2>.
--
-- <NewE> is the new edge created from <E>. <NewF1>
-- (resp. <NewF2>) is the new face created from <F1>
