CGAL::Random_access_adaptor< IC > Class Template Reference

#include <CGAL/iterator.h>

Definition

template<typename IC>
class CGAL::Random_access_adaptor< IC >

The class Random_access_adaptor provides a random access for data structures.

Either the data structure supports random access iterators or circulators where this class maps function calls to the iterator or circulator, or a STL std::vector is used to provide the random access. The iterator or circulator of the data structure are of type IC.

Types
typedef unspecified_type	size_type
	size type of the STL std::vector.

Creation
	Random_access_adaptor ()
	invalid index.
	Random_access_adaptor (const IC &i)
	empty random access index initialized to start at i.
	Random_access_adaptor (const IC &i, const IC &j)
	random access index initialized to the range [i,j).
void	reserve (size_type r)
	reserve r entries, if a std::vector is used internally.

Operations
IC	operator[] (size_type n)
	returns iterator or circulator to the n-th item.
void	push_back (const IC &k)
	adds k at the end of the indices.
