Class SimpleSpreadSheet

java.lang.Object
  quadbase.util.SimpleSpreadSheet

All Implemented Interfaces:

ISpreadSheetModel

public class SimpleSpreadSheet
extends java.lang.Object
implements ISpreadSheetModel

This class provides a simple implementation for the ISpreadSheetModel interface. Data is read from arrays and maintained in memory.

Note : the row and column label array lengths always determine the size of the spreadsheet. The cell values are adjusted accordingly. The cells are initially default to null, and are later assigned as provided in the cell array.
