Interface Summary

Interface	Description
MemoryBlockIterator	The memory block iterator is an iterator that always buffers a block of elements in memory.
ResettableIterator<E>	The resettable iterator is a specialization of the iterator, allowing to reset the iterator and re-retrieve elements.
ResettableMutableObjectIterator<E>	The resettable iterator is a specialization of the iterator, allowing to reset the iterator and re-retrieve elements.
