Definition

template<typename Traits, typename HalfedgeDSItems, typename Alloc>
class CGAL::HalfedgeDS_vector< Traits, HalfedgeDSItems, Alloc >

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.
