CGAL 5.5.3 - Handles and Circulators
|
#include <CGAL/circulator.h>
The circulator traits class distinguishes between circulators and iterators.
It defines a local type category
that is identical to the type Circulator_tag
if the iterator category of the argument C
is a circulator category. Otherwise it is identical to the type Iterator_tag
.
The local type iterator_category
gives the corresponding iterator category for circulators, i.e. one of forward_iterator_tag
, bidirectional_iterator_tag
, or random_access_iterator_tag
.
The local type circulator_category
gives the corresponding circulator category for iterators, i.e. one of Forward_circulator_tag
, Bidirectional_circulator_tag
, or Random_access_circulator_tag
.
Example
A generic function bar()
that distinguishes between a call with a circulator range and a call with an iterator range:
Types | |
typedef unspecified_type | category |
either Iterator_tag or Circulator_tag . | |
typedef unspecified_type | iterator_category |
corresponding iterator category for circulators. | |
typedef unspecified_type | circulator_category |
corresponding circulator category for iterator. | |
