HSSFHeader

public class HSSFHeader extends Object
Class to read and manipulate the header.

The header works by having a left, center, and right side. The total cannot be more that 255 bytes long. One uses this class by getting the HSSFHeader from HSSFSheet and then getting or setting the left, center, and right side. For special things (such as page numbers and date), one can use a the methods that return the characters used to represent these. One can also change the fonts by using similar methods.
