Detailed Description

template<typename Iterator>
struct boost::gil::IteratorAdaptorConcept< Iterator >

Iterator adaptor is a forward iterator adapting another forward iterator.

In addition to GIL iterator requirements, GIL iterator adaptors must provide the following metafunctions:

• is_iterator_adaptor<Iterator>: Returns std::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.

concept IteratorAdaptorConcept<boost_concepts::ForwardTraversalConcept Iterator>
{
    where SameType<is_iterator_adaptor<Iterator>::type, std::true_type>;
 
    typename iterator_adaptor_get_base<Iterator>;
        where Metafunction<iterator_adaptor_get_base<Iterator> >;
        where boost_concepts::ForwardTraversalConcept<iterator_adaptor_get_base<Iterator>::type>;
 
    typename another_iterator;
    typename iterator_adaptor_rebind<Iterator,another_iterator>::type;
        where boost_concepts::ForwardTraversalConcept<another_iterator>;
        where IteratorAdaptorConcept<iterator_adaptor_rebind<Iterator,another_iterator>::type>;
 
    const iterator_adaptor_get_base<Iterator>::type& Iterator::base() const;
};
