Modifier and Type	Method	Description
`S2Edge`	`edgeFromTo(int index)`	Mark the `S2Polygon.S2LoopSequenceIndex.edgeFromTo(int)` method abstract again, so children of this class must implement it without using `S2Polygon.S2LoopSequenceIndex.edgeFrom(int)` and `S2Polygon.S2LoopSequenceIndex.edgeTo(int)`.
`private static int[]`	`getVertices(S2Polygon poly)`	Returns number of vertices per loop.
