## 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...
