public interface GroundedIterator<T extends Item>
extends SequenceIterator<T>

This interface is an extension to the SequenceIterator interface; it represents a SequenceIterator that is based on an in-memory representation of a sequence, and that is therefore capable of returned a SequenceValue containing all the items in the sequence.
