Class HSSFCellUtil

java.lang.Object

org.apache.poi.hssf.util.HSSFCellUtil

public final class HSSFCellUtil
extends java.lang.Object

Various utility functions that make working with a cells and rows easier. The various methods that deal with style's allow you to create your HSSFCellStyles as you need them. When you apply a style change to a cell, the code will attempt to see if a style already exists that meets your needs. If not, then it will create a new style. This is to prevent creating too many styles. there is an upper limit in Excel on the number of styles that can be supported.
