struct boost::gil::IteratorAdaptorConcept&lt; Iterator &gt;</h3>

<p>Iterator adaptor is a forward iterator adapting another forward iterator. </p>
<p>In addition to GIL iterator requirements, GIL iterator adaptors must provide the following metafunctions:</p><ul>
<li><code>is_iterator_adaptor&lt;Iterator&gt;</code>: Returns <code>std::true_type</code> </li>
<li><code>iterator_adaptor_get_base&lt;Iterator&gt;</code>: Returns the base iterator type</li>
<li><code>iterator_adaptor_rebind&lt;Iterator,NewBase&gt;</code>: Replaces the base iterator with the new one</li>
</ul>
<p>The adaptee can be obtained from the iterator via the "base()" method.</p>
