ArrangementDcelWithRebind Concept Reference
DCEL Concepts

## Definition

The concept `ArrangementDcelWithRebind` refines the `ArrangementDcel` concept by adding a policy clone idiom in form of a rebind struct-template.

Instantiate a dcel class with many different possible types without ad-hoc limitations on type of the dcel classes.

Refines:
  `ArrangementDcel`

Has Models:

  `CGAL::Arr_default_dcel<Traits>`

  `CGAL::Arr_face_extended_dcel<Traits,FData,V,H,F>`

  `CGAL::Arr_extended_dcel<Traits,VData,HData,FData,V,H,F>`

typedef unspecified_type ArrangementDcelWithRebind::rebind

allows the instantiation of a model of the base concept `ArrangementDcel` with a different possible geometry-traits class without ad-hoc limitations on it.

Following the standard clone policy, the rebind struct-template must have a nested type named `other` that defines the type of the model replica.
