Interface Cell

All Known Implementing Classes:
  HSSFCell, SXSSFCell, XSSFCell

    public interface Cell

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 conatin 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.

    @Deprecated
    @Removal(version="4.0")
    void setCellType(int cellType)

  Deprecated. POI 3.15 beta 3. Use `setCellType(CellType)` instead.

  Set the cells type (numeric, formula or string).

  If the cell currently contains a value, the value will be converted to match the new type, if possible. Formatting is generally lost in the process however.

  If what you want to do is get a String value for your numeric cell, stop!. This is not the way to do it. Instead, for fetching the string value of a numeric or boolean or date cell, use `DataFormatter` instead.

  Throws:
    `java.lang.IllegalArgumentException` - if the specified cell type is invalid
    `java.lang.IllegalStateException` - if the current value cannot be converted to the new type
  See Also:
    `CellType.NUMERIC`, `CellType.STRING`, `CellType.FORMULA`, `CellType.BLANK`, `CellType.BOOLEAN`, `CellType.ERROR`

### setCellType

    void setCellType(CellType cellType)

  Set the cells type (numeric, formula or string).

  If the cell currently contains a value, the value will be converted to match the new type, if possible. Formatting is generally lost in the process however.

  If what you want to do is get a String value for your numeric cell, stop!. This is not the way to do it. Instead, for fetching the string value of a numeric or boolean or date cell, use `DataFormatter` instead.

  Throws:
    `java.lang.IllegalArgumentException` - if the specified cell type is invalid
    `java.lang.IllegalStateException` - if the current value cannot be converted to the new type

### getCellType

    @Deprecated
    int getCellType()

  Deprecated. POI 3.15. Will return a `CellType` enum in the future.

  Return the cell type. Will return `CellType` in version 4.0 of POI. For forwards compatibility, do not hard-code cell type literals in your code.

  Returns:
    the cell type

### getCellTypeEnum

    @Removal(version="4.2")
    CellType getCellTypeEnum()

  Return the cell type.

  Returns:
    the cell type
  Since:
    POI 3.15 beta 3 Will be renamed to `getCellType()` when we make the CellType enum transition in POI 4.0. See bug 59791.

### getCachedFormulaResultType

    @Deprecated
    int getCachedFormulaResultType()

  Deprecated. 3.15. Will return a `CellType` enum in the future.

  Only valid for formula cells Will return `CellType` in a future version of POI. For forwards compatibility, do not hard-code cell type literals in your code.

  Returns:
    one of (`CellType.NUMERIC`, `CellType.STRING`, `CellType.BOOLEAN`, `CellType.ERROR`) depending on the cached value of the formula

### getCachedFormulaResultTypeEnum

    CellType getCachedFormulaResultTypeEnum()

  Only valid for formula cells

  Returns:
    one of (`CellType.NUMERIC`, `CellType.STRING`, `CellType.BOOLEAN`, `CellType.ERROR`) depending on the cached value of the formula
  Since:
    POI 3.15 beta 3 Will be renamed to `getCachedFormulaResultType()` when we make the CellType enum transition in POI 4.0. See bug 59791.

### setCellValue

    void setCellValue(double value)

  Set a numeric value for the cell

  Parameters:
    `value` - the numeric value to set this cell to. For formulas we'll set the precalculated value, for numerics we'll set its value. For other types we will change the cell to a numeric cell and set its value.

### setCellValue

    void setCellValue(java.util.Date value)

  Converts the supplied date to its equivalent Excel numeric value and sets that into the cell.

  Note - There is actually no 'DATE' cell type in Excel. In many cases (when entering date values), Excel automatically adjusts the cell style to some date format, creating the illusion that the cell data type is now something besides `CellType.NUMERIC`. POI does not attempt to replicate this behaviour. To make a numeric cell display as a date, use `setCellStyle(CellStyle)` etc.

  Parameters:
    `value` - the numeric value to set this cell to. For formulas we'll set the precalculated value, for numerics we'll set its value. For other types we will change the cell to a numerics cell and set its value.

### setCellValue

    void setCellValue(java.util.Calendar value)

  Set a date value for the cell. Excel treats dates as numeric so you will need to format the cell as a date.

  This will set the cell value based on the Calendar's timezone. As Excel does not support timezones this means that both 20:00+03:00 and 20:00-03:00 will be reported as the same value (20:00) even that there are 6 hours difference between the two times. This difference can be preserved by using `setCellValue(value.getTime())` which will automatically shift the times to the default timezone.

  Parameters:
    `value` - the date value to set this cell to. For formulas we'll set the precalculated value, for numerics we'll set its value. For othertypes we will change the cell to a numeric cell and set its value.

### setCellValue

    void setCellValue(RichTextString value)

  Set a rich string value for the cell.

  Parameters:
    `value` - value to set the cell to. For formulas we'll set the formula string, for String cells we'll set its value. For other types we will change the cell to a string cell and set its value. If value is null then we will change the cell to a Blank cell.

### setCellValue

    void setCellValue(java.lang.String value)

  Set a string value for the cell.

  Parameters:
    `value` - value to set the cell to. For formulas we'll set the formula string, for String cells we'll set its value. For other types we will change the cell to a string cell and set its value. If value is null then we will change the cell to a Blank cell.

### setCellFormula

    void setCellFormula(java.lang.String formula)
                        throws FormulaParseException

  Sets formula for this cell.

  Note, this method only sets the formula string and does not calculate the formula value. To set the precalculated value use `setCellValue(double)` or `setCellValue(String)`

  Parameters:
    `formula` - the formula to set, e.g. `"SUM(C4:E4)"`. If the argument is `null` then the current formula is removed.
  Throws:
    `FormulaParseException` - if the formula has incorrect syntax or is otherwise invalid

### getCellFormula

    java.lang.String getCellFormula()

  Return a formula for the cell, for example, `SUM(C4:E4)`

  Returns:
    a formula for the cell
  Throws:
    `java.lang.IllegalStateException` - if the cell type returned by `getCellTypeEnum()` is not `CellType.FORMULA`

### getNumericCellValue

    double getNumericCellValue()

  Get the value of the cell as a number.

  For strings we throw an exception. For blank cells we return a 0. For formulas or error cells we return the precalculated value;

  Returns:
    the value of the cell as a number
  Throws:
    `java.lang.IllegalStateException` - if the cell type returned by `getCellTypeEnum()` is `CellType.STRING`
    `java.lang.NumberFormatException` - if the cell value isn't a parsable `double`.
  See Also:
    `for turning this number into a string similar to that which Excel would render this number as.`

### getDateCellValue

    java.util.Date getDateCellValue()

  Get the value of the cell as a date.

  For strings we throw an exception. For blank cells we return a null.

  Returns:
    the value of the cell as a date
  Throws:
    `java.lang.IllegalStateException` - if the cell type returned by `getCellTypeEnum()` is `CellType.STRING`
    `java.lang.NumberFormatException` - if the cell value isn't a parsable `double`.
  See Also:
    `for formatting this date into a string similar to how excel does.`

### getRichStringCellValue

    RichTextString getRichStringCellValue()

  Get the value of the cell as a XSSFRichTextString

  For numeric cells we throw an exception. For blank cells we return an empty string. For formula cells we return the pre-calculated value if a string, otherwise an exception.
