|
|
A type `Key` is a model of the concept `Hashable` if the
|
|
specializations `boost::hash<Key>` and `std::hash<Key>` exist.
|
|
|
|
\cgalHasModel All handles and indices of \cgal data structures.
|
|
\cgalHasModel All handles of OpenMesh, by including the specializations
|
|
of the `graph_traits` header files provided by \cgal.
|
|
They can be disables by defining the macro `CGAL_DISABLE_HASH_OPENMESH`.
