## Inherits from

Arr_halfedge_base< X_monotone_curve_2 >.

## Definition

An instance of this teplate serves as a basis type for any halfedge record of the Dcel class used by instances of the General_polygon_set_2 `and`General_polygon_with_holes_2` class templates.

The `X_monotone_curve_2` template parameter is the type of \( x\)-monotone curves associated with the halfedges.

You need to extend this template with auxiliary data only if you intend to obtain the underlying arrangement of the general polygon set and process it further.

Is Model Of:
  `GeneralPolygonSetDcelHalfedge`
