  +--jxl.biff.CellReferenceHelper

public class CellReferenceHelper
extends java.lang.Object

A helper to transform between excel cell references and sheet:column:row notation Because this function will be called when generating a string representation of a formula, the cell reference will merely be appened to the string buffer instead of returning a full blooded string, for performance reasons
