Class BBoxCalculator

java.lang.Object
org.locationtech.spatial4j.shape.impl.BBoxCalculator

public class BBoxCalculator extends Object
(INTERNAL) Calculates the minimum bounding box given a bunch of rectangles (ranges). It's a temporary object and not thread-safe; throw it away when done. For a cartesian space, the calculations are trivial but it is not for geodetic. For geodetic, it must maintain an ordered set of disjoint ranges as each range is provided.
