C is the new geometry of the edge,
L is the new location, and

pure virtual

Returns true if the face, F, has been modified. If the face has been modified:

S is the new geometry of the face,
L is its new location, and
Tol is the new tolerance. The flag, RevWires, is set to true when the modification reverses the normal of the surface, (i.e. the wires have to be reversed). The flag, RevFace, is set to true if the orientation of the modified face changes in the shells which contain it. If the face has not been modified this function returns false, and the values of S, L, Tol, RevWires and RevFace are not significant.
