getCellType in interface Cell

Returns:

the cell type

getCellTypeEnum

@Deprecated

getCellTypeEnum in interface Cell

Returns:

the cell type

Since:

POI 3.15 beta 3

getCachedFormulaResultType

public CellType getCachedFormulaResultType()

Only valid for formula cells

getCachedFormulaResultType in interface Cell

Returns:

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

getCachedFormulaResultTypeEnum

setCellValue

public void setCellValue(double value)

Set a numeric value for the cell

Specified by:

setCellValue in interface 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

public void setCellValue(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.

Specified by:

setCellValue in interface 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 numerics cell and set its value.

setCellValue

public void setCellValue(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.

setCellValue

public void setCellValue(RichTextString value)

Set a rich string value for the cell.

Specified by:

setCellValue in interface 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

public void setCellValue(String value)

Set a string value for the cell.

Specified by:

setCellValue in interface 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

public void setCellFormula(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)

Specified by:
