Method Detail

### parse

    public static Ptg[] parse(java.lang.String formula,
                              HSSFWorkbook workbook)
                       throws FormulaParseException

  Convenience method for parsing cell formulas. see `parse(String, HSSFWorkbook, int, int)`

  Throws:
    `FormulaParseException`

### parse

    public static Ptg[] parse(java.lang.String formula,
                              HSSFWorkbook workbook,
                              int formulaType)
                       throws FormulaParseException

  Parameters:
    `formulaType` - a constant from `FormulaType`
  Returns:
    the parsed formula tokens
  Throws:
    `FormulaParseException` - if the formula has incorrect syntax or is otherwise invalid

### parse

    public static Ptg[] parse(java.lang.String formula,
                              HSSFWorkbook workbook,
                              int formulaType,
                              int sheetIndex)
                       throws FormulaParseException

  Parameters:
    `formula` - the formula to parse
    `workbook` - the parent workbook
    `formulaType` - a constant from `FormulaType`
    `sheetIndex` - the 0-based index of the sheet this formula belongs to. The sheet index is required to resolve sheet-level names. `-1` means that the scope of the name will be ignored and the parser will match named ranges only by name
  Returns:
    the parsed formula tokens
  Throws:
    `FormulaParseException` - if the formula has incorrect syntax or is otherwise invalid

### toFormulaString

    public static java.lang.String toFormulaString(HSSFWorkbook book,
                                                   Ptg[] ptgs)

  Static method to convert an array of `Ptg`s in RPN order to a human readable string format in infix mode.

  Parameters:
    `book` - used for defined names and 3D references
    `ptgs` - must not be `null`
  Returns:
    a human readable String
