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.
