Interface FlatHashIterator

All Superinterfaces:

HierarchyItem

public interface FlatHashIterator
extends HierarchyItem

Define an iterator over the primitive type 'long'. We do this because Iterators in Java can have Object generic types, not primitive types, and we want to avoid auto-boxing for performances reasons. Additionally, we use this interface to iterate over hashes of a same depth given by the HierarchyItem.depth() method.
