boost::gil::IteratorAdaptorConcept
Iterator adaptor is a forward iterator adapting another forward iterator.
Synopsis
Declared in <boost/gil/concepts/pixel_iterator.hpp>
template<typename Iterator>
struct IteratorAdaptorConcept;Description
In addition to GIL iterator requirements, GIL iterator adaptors must provide the following metafunctions:
-
is_iterator_adaptor<Iterator>Returnsstd::true_type -
iterator_adaptor_get_base<Iterator>Returns the base iterator type -
iterator_adaptor_rebind<Iterator,NewBase>Replaces the base iterator with the new one
The adaptee can be obtained from the iterator via the "base()" method.
