## Definition

template<class NefPolyhedronTraits_3, class NefPolyhedronItems_3 = CGAL::Default_items<NefPolyhedronTraits_3> class Nef_polyhedronMarks = bool>
class CGAL::Nef_polyhedron_3< NefPolyhedronTraits_3, NefPolyhedronItems_3 >::Halffacet_cycle_iterator

The type `Halffacet_cycle_iterator` iterates over a list of `Object_handles`.

Each item of that list can either be assigned to `SHalfedge_handle` or `SHalfloop_handle`. To find out which of these assignment works out, the member functions `is_shalfedge()` and `is_shalfloop()` are provided.

## Types
typedef unspecified_type | SHalfedge_handle
| const handle to SHalfedge.
typedef unspecified_type | SHalfloop_handle
| const handle to SHalfloop.

## Creation
| Halffacet_cycle_iterator ()
| default constructor.

## Operations
bool | is_shalfedge () const
| returns true if `hfc` represents a `SHalfedge_handle`.
bool | is_shalfloop () const
| returns true if `hfc` represents a `SHalfloop_handle`.
| operator SHalfedge_handle () const
| casts `hfc` to `SHalfedge_handle`.
| operator SHalfloop_handle () const
| casts `hfc` to `SHalfloop_handle`.
