## Classes

class | dereference_iterator_adaptor
| An adaptor over an existing iterator that provides for custom filter on dereferencing the object. Models: IteratorAdaptorConcept, PixelIteratorConcept. More...
struct | iterator_add_deref
| Returns the type (and creates an instance) of an iterator that invokes the given dereference adaptor upon dereferencing. More...
struct | iterator_add_deref< dereference_iterator_adaptor< Iterator, PREV_DEREF >, Deref >
| For dereference iterator adaptors, compose the new function object after the old one. More...
