MoveNext()

int Loyc.Collections.Impl.IEnumeratorFrame< Frame, T >.MoveNext	(	ref Frame	frame,
		ref T	current
	)

Enumerates the next item, or the next child collection.

Parameters

frame	Current frame (on entry, 'frame' is the same as 'this'). To begin enumerating a child frame, this method must change 'frame' to the desired child frame and return -1.
current	Current item (on entry, 'current' is value most recently enumerated by NestedEnumerator<Frame,T>.) To enumerate an item, MoveNext must change the value of 'current' and return 1.

Returns

1 to enumerate 'current', 0 when there are no more items in this frame's sequence, and any other value to enumerate a child frame.
