package iterator

// Defines one of the base iterators, the All iterator. Which, logically
// enough, represents all nodes or all links in the graph.
//
// This particular file is actually vestigial. It's up to the QuadStore to give
// us an All iterator that represents all things in the graph. So this is
// really the All iterator for the memstore.QuadStore. That said, it *is* one of
// the base iterators, and it helps just to see it here.
