GroupIterator

trait GroupIterator[A] extends Iterator[A]

Iterator facilitating group-wise iteration over two ore more levels. Each level is represented by an inner iterator. Interactions between these levels are handled internally thus the implementor just needs to define the individual level iterators. Level iterator implementations will typically be inner objects inheriting from the public inner traits of this trait.

This trait is not graph-specific.

A

Simple or composite type of elements being subject to the iteration. For instance, a two-level iteration could expose just the elements of the inner loop or both the outer and the inner loop elements as a tuple.
