Class HSSFCell

  • All Implemented Interfaces:
    Cell

    public class HSSFCell
    extends CellBase
    High level representation of a cell in a row of a spreadsheet. Cells can be numeric, formula-based or string-based (text). The cell type specifies this. String cells cannot contain numbers and numeric cells cannot contain strings (at least according to our model). Client apps should do the conversions themselves. Formula cells have the formula string, as well as the formula result, which can be numeric or string.

    Cells should have their number (0 based) before being added to a row. Only cells that have values should be added.

                           short col)
        Creates new Cell - Should only be called by HSSFRow. This creates a cell from scratch.

        When the cell is initially created it is set to CellType.BLANK. Cell types can be changed/overwritten by calling setCellValue with the appropriate type as a parameter although conversions from one type to another may be prohibited.

        Parameters:
        book - - Workbook record of the workbook containing this cell
        sheet - - Sheet record of the sheet containing this cell
        row - - the row of this cell
        col - - the column for this cell
