    • Method Detail

      • 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:
        java.lang.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:
        java.lang.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:
        java.lang.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(int, org.apache.poi.ss.usermodel.Row.MissingCellPolicy)

      • 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:
        java.lang.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)

      • 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

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

      • spliterator

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