Class XSSFCell

java.lang.Object
  org.apache.poi.xssf.usermodel.XSSFCell

All Implemented Interfaces:

Cell

public final class XSSFCell
extends java.lang.Object
implements 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 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.

XSSFCell

protected XSSFCell(XSSFRow row,
                   org.openxmlformats.schemas.spreadsheetml.x2006.main.CTCell cell)

Construct a XSSFCell.

Parameters:

row - the parent row.

cell - the xml bean containing information about the cell.

getCellType

@Deprecated
@Removal(version="3.17")
public int getCellType()

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

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

Specified by:

getCellType in interface Cell

Returns:

the cell type

getCellTypeEnum

public CellType getCellTypeEnum()

Return the cell type. Tables in an array formula return CellType.FORMULA for all cells, even though the formula is only defined in the OOXML file for the top left cell of the array.

NOTE: POI does not support data table formulas. Cells in a data table appear to POI as plain cells typed from their cached value.

Specified by:

getCellTypeEnum in interface Cell

Returns:

the cell type

Since:

POI 3.15 beta 3 Will be deleted when we make the CellType enum transition. See bug 59791.

getCachedFormulaResultType

@Deprecated
@Removal(version="3.17")
public 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.

Specified by:

getCachedFormulaResultType in interface Cell

Returns:

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

getCachedFormulaResultTypeEnum

public CellType getCachedFormulaResultTypeEnum()

Only valid for formula cells

Specified by:

getCachedFormulaResultTypeEnum in interface Cell

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 deleted when we make the CellType enum transition. See bug 59791.

getDateCellValue

public 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.

Specified by:

getDateCellValue in interface Cell

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.

setCellValue

public void setCellValue(java.util.Date value)

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

Specified by:

setCellValue in interface Cell

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 other types we will change the cell to a numeric cell and set its value.

setCellValue

public 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.

Specified by:

setCellValue in interface Cell

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.
