Method Detail

ensureCellAreaSize

public void ensureCellAreaSize(int rows,
                               int cols,
                               boolean shrink)

Ensures that the cell area has the specified number of rows and columns. If the current size of the cell area is different than the specified size, and either the current size is smaller than the specified size or the 'shrink' parameter is true, the cell area is resized accordingly.

Parameters:

rows - The number of rows in the cell area

cols - The number of columns in the cell area

shrink - Specifies whether to shrink the cell area if necessary

storeCellValues

public void storeCellValues(SpreadsheetCache.SheetValues sheetValues)

Stores the cell values in the provided SheetValues object into the cell area.

Parameters:

sheetValues - The SheetValues object containing the cell values to store

getCachedCellValue

public java.lang.Object getCachedCellValue(int row,
                                           int col,
