		Halfedge_handle	,
		Vertex_handle	,
		Vertex_handle
	)		[inline]

Handle the a subcurve that overlaps a given edge.

Parameters:

cv	The overlapping subcurve.
he	The overlapped halfedge (directed from left to right).
left_v	The vertex that corresponds to the left endpoint of cv (or an invalid handle if no such arrangement vertex exists).
right_v	The vertex that corresponds to the right endpoint of cv (or an invalid handle if no such arrangement vertex exists).

Returns:

A handle to the halfedge obtained from the insertion of the overlapping subcurve into the arrangement.

		Vertex_handle	right_v,

	)		[inline]

Handle the a subcurve located in the interior of a given face.

Parameters:

cv	The subcurve.
face	The face containing cv's interior.
left_v	The vertex that corresponds to the left endpoint of cv (or an invalid handle if no such arrangement vertex exists).
left_he	The halfedge that contains the left endpoint of cv (or an invalid handle if no such halfedge exists).
right_v	The vertex that corresponds to the right endpoint of cv (or an invalid handle if no such arrangement vertex exists).
right_he	The halfedge that contains the right endpoint of cv (or an invalid handle if no such halfedge exists).

Returns:

A handle to the halfedge obtained from the insertion of the subcurve into the arrangement.
