#include <Concepts/TriangulationDSFullCell.h>

Definition

The concept TriangulationDSFullCell describes the requirements for the full cell class of a CGAL::Triangulation_data_structure. It refines the concept TriangulationDataStructure::FullCell.

Since the CGAL::Triangulation_data_structure is the class which defines the handle types, the full cell base class has to be somehow parameterized by the triangulation data structure. But since the CGAL::Triangulation_data_structure itself is parameterized by the cell and vertex base classes, there is a cycle in the definition of these classes. In order to break the cycle, the base classes for cells and vertices which are plugged in to instantiate a Triangulation_data_structure use a void as triangulation data structure parameter. Then, the CGAL::Triangulation_data_structure uses a rebind mechanism (similar to the one specified in std::allocator) in order to plug itself as parameter in the full cell and vertex base classes. This mechanism requires that the base class provides a templated nested class Rebind_TDS that itself provides the subtype Rebind_TDS::Other which is the rebound version of the base class. This rebound base class is the class that the CGAL::Triangulation_data_structure actually uses as a base class for the class of CGAL::Triangulation_data_structure::Vertex.

Creation
If you want to create a full cell as part of a `TriangulationDataStructure`, you would rather want to call the `new_full_cell()` from the latter concept, as it is not possible to incorporate an existing external full cell into a triangulation.

Memory Management
These member functions are required by `Triangulation_data_structure` because it uses `Compact_container` to store its cells. See the documentation of `Compact_container` for the exact requirements.

Member Typedef Documentation

◆ Rebind_TDS

template<typename TDS2 >

using TriangulationDSFullCell::Rebind_TDS = unspecified_type

This nested template class has to define a type Rebind_TDS<TDS2>::Other which is the rebound vertex, that is, the one that will be actually used by Triangulation_data_structure.

The Rebind_TDS<TDS2>::Other type will be the real base class of Triangulation_data_structure::Full_cell.

Note: It can be implemented using a nested template class.

◆ Triangulation_data_structure

typedef unspecified_type TriangulationDSFullCell::Triangulation_data_structure

The Triangulation_data_structure in which the TriangulationDSFullCell is defined/used.

Must be a model of the TriangulationDataStructure concept.
