the value 0 if the row number of this XSSFRow is equal to the row number of the argument XSSFRow; a value less than 0 if the row number of this this XSSFRow is numerically less than the row number of the argument XSSFRow; and a value greater than 0 if the row number of this this XSSFRow is numerically greater than the row number of the argument XSSFRow.

public XSSFCell createCell(int columnIndex,
                           int type)
Use this to create new cells within the row and return it.

Specified by:

Parameters:
columnIndex - - the column number this cell represents
type - - the cell's data type
Returns:
XSSFCell a high level representation of the created cell.
Throws:
java.lang.IllegalArgumentException - if the specified cell type is invalid, columnIndex < 0 or greater than 16384, the maximum number of columns supported by the SpreadsheetML format (.xlsx)
See Also:
Cell.CELL_TYPE_BLANK, Cell.CELL_TYPE_BOOLEAN, Cell.CELL_TYPE_ERROR, Cell.CELL_TYPE_FORMULA, Cell.CELL_TYPE_NUMERIC, Cell.CELL_TYPE_STRING

getCell

public XSSFCell getCell(int cellnum)
Returns the cell at the given (0 based) index, with the Row.MissingCellPolicy from the parent Workbook.

Specified by:
getCell in interface Row
Parameters:
cellnum - 0 based column number
Returns:
the cell at the given (0 based) index
See Also:
Row.getCell(int, org.apache.poi.ss.usermodel.Row.MissingCellPolicy)

getCell

public XSSFCell getCell(int cellnum,
                        Row.MissingCellPolicy policy)
Returns the cell at the given (0 based) index, with the specified Row.MissingCellPolicy

Specified by:
getCell in interface Row
Returns:
the cell at the given (0 based) index
Throws:
java.lang.IllegalArgumentException - if cellnum < 0 or the specified MissingCellPolicy is invalid
See Also:
Row.RETURN_NULL_AND_BLANK, Row.RETURN_BLANK_AS_NULL, Row.CREATE_NULL_AS_BLANK

getFirstCellNum

public short getFirstCellNum()
Get the number of the first cell contained in this row.

Specified by:
getFirstCellNum in interface Row
Returns:
short representing the first logical cell in the row, or -1 if the row does not contain any cells.

getLastCellNum

public short getLastCellNum()
Gets the index of the last cell contained in this row PLUS ONE. The result also happens to be the 1-based column number of the last cell. This value can be used as a standard upper bound when iterating over cells:
 short minColIx = row.getFirstCellNum();
 short maxColIx = row.getLastCellNum();
 for(short colIx=minColIx; colIx<maxColIx; colIx++) {
   XSSFCell cell = row.getCell(colIx);
   if(cell == null) {
     continue;
   }
   //... do something with cell
 }
 

Specified by:

Returns:
short representing the last logical cell in the row PLUS ONE, or -1 if the row does not contain any cells.

getHeight

public short getHeight()
Get the row's height measured in twips (1/20th of a point). If the height is not set, the default worksheet value is returned, See XSSFSheet.getDefaultRowHeightInPoints()

Specified by:
getHeight in interface Row
Returns:
row height measured in twips (1/20th of a point)

getHeightInPoints

public float getHeightInPoints()
Returns row height measured in point size. If the height is not set, the default worksheet value is returned, See XSSFSheet.getDefaultRowHeightInPoints()
