Interface Summary

Interface	Description
Cell	Represents a grid cell.
CellCanPrune	Grid cells that share nothing with other cells when calling Cell.getNextLevelCells(Shape) might implement this interface.
S2ShapeFactory	Shape factory for Spatial contexts that support S2 geometry.

Class Summary

Class	Description
CellIterator	An Iterator of SpatialPrefixTree Cells.
GeohashPrefixTree	A SpatialPrefixTree based on Geohashes.
GeohashPrefixTree.Factory	Factory for creating GeohashPrefixTree instances with useful defaults
LegacyCell	The base for the original two SPT's: Geohash and Quad.
