Class Region

java.lang.Object

loci.poi.hssf.util.Region

All Implemented Interfaces:

Comparable

public class Region
extends Object
implements Comparable

Represents a from/to row/col square. This is a object primitive that can be used to represent row,col - row,col just as one would use String to represent a string of characters. Its really only useful for HSSF though.
