Method Stats

graph/iterator.go:117–117

These methods relate to choosing the right iterator, or optimizing an iterator tree Stats() returns the relative costs of calling the iteration methods for this iterator, as well as the size. Roughly, it will take NextCost * Size "cost units" to get everything out of the iterator. This is a wibbly-

	// "cost units" to get everything out of the iterator. This is a wibbly-wobbly

	Stats() IteratorStats

	// Helpful accessor for the number of things in the iterator. The first return
	// value is the size, and the second return value is whether that number is exact,
