  • Method Details

    • createCell

      Cell createCell(int column)
      Use this to create new cells within the row and return it.

      The cell that is returned is a CellType.BLANK. The type can be changed either through calling setCellValue or setCellType.

      Parameters:
      column - - the column number this cell represents
      Returns:
      Cell a high level representation of the created cell.
      Throws:
      IllegalArgumentException - if columnIndex < 0 or greater than the maximum number of supported columns (255 for *.xls, 1048576 for *.xlsx)

    • createCell

      Cell createCell(int column, CellType type)
      Use this to create new cells within the row and return it.

      The cell that is returned will be of the requested type. The type can be changed either through calling setCellValue or setCellType, but there is a small overhead to doing this, so it is best to create of the required type up front.

      Parameters:
      column - - the column number this cell represents
      type - - the cell's data type
      Returns:
      Cell a high level representation of the created cell.
      Throws:
      IllegalArgumentException - if columnIndex < 0 or greater than a maximum number of supported columns (255 for *.xls, 1048576 for *.xlsx)

    • removeCell

      void removeCell(Cell cell)
      Remove the Cell from this row.
      Parameters:
      cell - the cell to remove

    • setRowNum

      void setRowNum(int rowNum)
      Set the row number of this row.
      Parameters:
      rowNum - the row number (0-based)
      Throws:
      IllegalArgumentException - if rowNum < 0

    • getRowNum

      int getRowNum()
      Get row number this row represents
      Returns:
      the row number (0 based)

    • getCell

      Cell getCell(int cellnum)
      Get the cell representing a given column (logical cell) 0-based. If you ask for a cell that is not defined....you get a null.
      Parameters:
      cellnum - 0 based column number
      Returns:
      Cell representing that column or null if undefined.
      See Also:

    • getCell

      Cell getCell(int cellnum, Row.MissingCellPolicy policy)
      Returns the cell at the given (0 based) index, with the specified Row.MissingCellPolicy
      Returns:
      the cell at the given (0 based) index
      Throws:
      IllegalArgumentException - if cellnum < 0 or the specified MissingCellPolicy is invalid

    • getFirstCellNum

      short getFirstCellNum()
      Get the number of the first cell contained in this row. Note: cells which had content before and were set to empty later might still be counted as cells by Excel and Apache POI, so the result of this method will include such rows and thus the returned value might be lower than expected!
      Returns:
      short representing the first logical cell in the row, or -1 if the row does not contain any cells.

    • getLastCellNum

      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++) {
   Cell cell = row.getCell(colIx);
   if(cell == null) {
     continue;
   }
   //... do something with cell
 }
      Note: cells which had content before and were set to empty later might still be counted as cells by Excel and Apache POI, so the result of this method will include such rows and thus the returned value might be higher than expected!
      Returns:
      short representing the last logical cell in the row PLUS ONE, or -1 if the row does not contain any cells.

    • getPhysicalNumberOfCells

      int getPhysicalNumberOfCells()
      Gets the number of defined cells (NOT number of cells in the actual row!). That is to say if only columns 0,4,5 have values then there would be 3.
      Returns:
      int representing the number of defined cells in the row.

    • setHeight

      void setHeight(short height)
      Set the row's height or set to ff (-1) for undefined/default-height. Set the height in "twips" or 1/20th of a point.
      Parameters:
      height - rowheight or 0xff for undefined (use sheet default)

    • setZeroHeight

      void setZeroHeight(boolean zHeight)
      Set whether or not to display this row with 0 height
      Parameters:
      zHeight - height is zero or not.

    • getZeroHeight

      boolean getZeroHeight()
      Get whether or not to display this row with 0 height
      Returns:
      - zHeight height is zero or not.

    • setHeightInPoints

      void setHeightInPoints(float height)
      Set the row's height in points.
      Parameters:
      height - the height in points. -1 resets to the default height

    • getHeight

      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 Sheet.getDefaultRowHeightInPoints()
      Returns:
      row height measured in twips (1/20th of a point)

    • getHeightInPoints

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

    • isFormatted

      boolean isFormatted()
      Is this row formatted? Most aren't, but some rows do have whole-row styles. For those that do, you can get the formatting from getRowStyle()

    • getRowStyle

      CellStyle getRowStyle()
      Returns the whole-row cell styles. Most rows won't have one of these, so will return null. Call isFormatted() to check first.

    • setRowStyle

      void setRowStyle(CellStyle style)
      Applies a whole-row cell styling to the row.

    • cellIterator

      Iterator<Cell> cellIterator()
      Returns:
      Cell iterator of the physically defined cells. Note element 4 may actually be row cell depending on how many are defined!

    • iterator

      default Iterator<Cell> iterator()
      Alias for cellIterator() to allow foreach loops: 
       for(Cell cell : row){
     ...
 }
      Specified by:
      iterator in interface Iterable<Cell>
      Returns:
      an iterator over cells in this row.

    • spliterator

      default Spliterator<Cell> spliterator()
      Specified by:
      spliterator in interface Iterable<Cell>
      Returns:
      Cell spliterator of the physically defined cells. Note element 4 may actually be row cell depending on how many are defined!
      Since:
      POI 5.2.0

    • getSheet

      Sheet getSheet()
      Returns the Sheet this row belongs to
      Returns:
      the Sheet that owns this row

    • getOutlineLevel

      int getOutlineLevel()
      Returns the rows outline level. Increased as you put it into more groups (outlines), reduced as you take it out of them.
