Classes
class	step_iterator_adaptor
	An adaptor over an existing iterator that changes the step unit. More...
struct	memunit_step_fn
	function object that returns the memory unit distance between two iterators and advances a given iterator a given number of mem units (bytes or bits) More...
class	memory_based_step_iterator
	Iterator with dynamically specified step in memory units (bytes or bits). Models StepIteratorConcept, IteratorAdaptorConcept, MemoryBasedIteratorConcept, PixelIteratorConcept, HasDynamicXStepTypeConcept. More...
