#include <CGAL/HalfedgeDS_vector.h>

Definition

The class HalfedgeDS_vector is a model for the HalfedgeDS concept.

HalfedgeDS_vector is a vector-based representation with random access iterators that does not support removal.

Is Model Of:
HalfedgeDS<Traits,Items,Alloc>

Implementation

HalfedgeDS_vector uses internally the STL std::vector container class. We require that we can create a std::vector::iterator from a pointer. If this will not be true any longer for any major STL distribution we might switch to an internal implementation of a vector.

The capacity is restricted to the reserved size. Allocations are not possible beyond the capacity without calling reserve again. All handles and iterators are invalidated upon a reserve call that increases the capacity.

CGAL_ALLOCATOR(int) is used as default argument for the Alloc template parameter.

Examples:
HalfedgeDS/hds_prog_compact.cpp, and HalfedgeDS/hds_prog_vector.cpp.
