      • createCell

        public HSSFCell 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.

        Specified by:
        createCell in interface Row
        Parameters:
        column - - the column number this cell represents
        Returns:
        HSSFCell a high level representation of the created cell.
        Throws:
        IllegalArgumentException - if columnIndex < 0 or greater than 255, the maximum number of columns supported by the Excel binary format (.xls)

      • createCell

        public HSSFCell createCell​(int columnIndex,
                           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 the required type up front.

        Specified by:
        createCell in interface Row
        Parameters:
        columnIndex - - the column number this cell represents
        type - - the cell's data type
        Returns:
        HSSFCell a high level representation of the created cell.
        Throws:
        IllegalArgumentException - if columnIndex < 0 or greater than 255, the maximum number of columns supported by the Excel binary format (.xls)

 short maxColIx = row.getLastCellNum();
 for(short colIx=minColIx; colIx<maxColIx; colIx++) {
   HSSFCell cell = row.getCell(colIx);
   if(cell == null) {

      • isFormatted

        public 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()
        Specified by:
        isFormatted in interface Row

      • getRowStyle

        public HSSFCellStyle getRowStyle()
        Returns the whole-row cell styles. Most rows won't have one of these, so will return null. Call isFormatted() to check first.
        Specified by:
        getRowStyle in interface Row

      • setRowStyle

        public void setRowStyle​(HSSFCellStyle style)
        Applies a whole-row cell styling to the row.

        cellIterator in interface Row
        Returns:
        cell iterator of the physically defined cells. Note that the 4th element might well not be cell 4, as the iterator will not return un-defined (null) cells. Call getCellNum() on the returned cells to know which cell they are. As this only ever works on physically defined cells, the Row.MissingCellPolicy has no effect.

      • compareTo

        public int compareTo​(HSSFRow other)
        Compares two HSSFRow objects. Two rows are equal if they belong to the same worksheet and their row indexes are equal.

        Parameters:
        other - the HSSFRow to be compared.
        Returns:
        • the value 0 if the row number of this HSSFRow is equal to the row number of the argument HSSFRow
        • a value less than 0 if the row number of this HSSFRow is numerically less than the row number of the argument HSSFRow
        • a value greater than 0 if the row number of this HSSFRow is numerically greater than the row number of the argument HSSFRow
        Throws:
        IllegalArgumentException - if the argument row belongs to a different worksheet

      • copyRowFrom

        @Beta
public void copyRowFrom​(Row srcRow,
                        CellCopyPolicy policy)
        Copy the cells from srcRow to this row If this row is not a blank row, this will merge the two rows, overwriting the cells in this row with the cells in srcRow If srcRow is null, overwrite cells in destination row with blank values, styles, etc per cell copy policy srcRow may be from a different sheet in the same workbook
        Parameters:
        srcRow - the rows to copy from
        policy - the policy to determine what gets copied

      • copyRowFrom

        @Beta
public void copyRowFrom​(Row srcRow,
                        CellCopyPolicy policy,
                        CellCopyContext context)
        Copy the cells from srcRow to this row. If this row is not a blank row, this will merge the two rows, overwriting the cells in this row with the cells in srcRow. If srcRow is null, overwrite cells in destination row with blank values, styles, etc per cell copy policy. Note that if you are copying from a non-HSSF row then you will need to disable style copying in the CellCopyPolicy (HSSF styles are not compatible with XSSF styles, for instance).
        Parameters:
        srcRow - the rows to copy from
        policy - the policy to determine what gets copied
        context - the context - see CellCopyContext
