Class SheetTransformer

java.lang.Object
  net.sf.jett.transform.SheetTransformer

public class SheetTransformer
extends java.lang.Object

A SheetTransformer knows how to transform one Sheet in an Excel spreadsheet. For cell processing, it creates a Block representing the entire Sheet, then it delegates processing to a BlockTransformer. It is also responsible for gathering all Formulas at the beginning, and replacing all Formulas with Excel Formulas at the end. It also exposes the "sheet" object in the "beans" Map.
