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...
