Class SimpleMBR2D

java.lang.Object

org.khelekore.prtree.SimpleMBR2D

All Implemented Interfaces:

MBR2D

public class SimpleMBR2D
extends Object
implements MBR2D

An implementation of MBR that keeps 4 double values for the actual min and max values needed.

Please note that you should not normally use this class when PRTree wants a MBR since this will actually use a lot of extra memory.
