CGAL::Random_access_adaptor<IC>

Definition

The class Random_access_adaptor<IC> 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.

#include <CGAL/iterator.h>

Types

Random_access_adaptor<IC>::size_type
	size type of the STL std::vector.

Creation

Random_access_adaptor<IC> random_access;
	invalid index.

Random_access_adaptor<IC> random_access ( IC i);
	empty random access index initialized to start at i.

Random_access_adaptor<IC> random_access ( IC i, IC j);
	random access index initialized to the range [i,j).

void	random_access.reserve ( size_type r)
		reserve r entries, if a std::vector is used internally.

Operations

random_access [ size_type n ]

returns iterator or circulator to the n-th item.

Precondition:

n < number of items in random_access.

void

random_access.push_back ( IC k)

adds k at the end of the indices.
