Package org.apache.poi.hssf.usermodel

Class HSSFSheet

  • All Implemented Interfaces:
    Iterable<Row>, Sheet
    public final class HSSFSheet
extends Object
implements Sheet
    High level representation of a worksheet.

    • Field Detail

      • INITIAL_CAPACITY

        public static final int INITIAL_CAPACITY
        Used for compile-time optimization. This is the initial size for the collection of rows. It is currently set to 20. If you generate larger sheets you may benefit by setting this to a higher number and recompiling a custom edition of HSSFSheet.

    • Method Detail

      • getWorkbook

        public HSSFWorkbook getWorkbook()
        Return the parent workbook
        Specified by:
        getWorkbook in interface Sheet
        Returns:
        the parent workbook

      • removeRow

        public void removeRow​(Row row)
        Remove a row from this sheet. All cells contained in the row are removed as well
        Specified by:
        removeRow in interface Sheet
        Parameters:
        row - representing a row to remove.

      • getRow

        public HSSFRow getRow​(int rowIndex)
        Returns the logical row (not physical) 0-based. If you ask for a row that is not defined you get a null. This is to say row 4 represents the fifth row on a sheet.
        Specified by:
        getRow in interface Sheet
        Parameters:
        rowIndex - row to get
        Returns:
        HSSFRow representing the row number or null if its not defined on the sheet

      • getPhysicalNumberOfRows

        public int getPhysicalNumberOfRows()
        Returns the number of physically defined rows (NOT the number of rows in the sheet)
        Specified by:
        getPhysicalNumberOfRows in interface Sheet
        Returns:
        the number of physically defined rows in this sheet

      • getFirstRowNum

        public int getFirstRowNum()
        Gets the first row on the sheet
        Specified by:
        getFirstRowNum in interface Sheet
        Returns:
        the number of the first logical row on the sheet, zero based

      • getLastRowNum

        public int getLastRowNum()
        Gets the number last row on the sheet. Owing to idiosyncrasies in the excel file format, if the result of calling this method is zero, you can't tell if that means there are zero rows on the sheet, or one at position zero. For that case, additionally call getPhysicalNumberOfRows() to tell if there is a row at position zero or not.
        Specified by:
        getLastRowNum in interface Sheet
        Returns:
        the number of the last row contained in this sheet, zero based.

        Specified by:
        setColumnHidden in interface Sheet
        Parameters:
        columnIndex - - the column to get (0-based)
        hidden - - the visiblity state of the column

      • isColumnHidden

        public boolean isColumnHidden​(int columnIndex)
        Get the hidden state for a given column.
        Specified by:
        isColumnHidden in interface Sheet
        Parameters:
        columnIndex - - the column to set (0-based)
        Returns:
        hidden - false if the column is visible

      • setColumnWidth

        public void setColumnWidth​(int columnIndex,
                           int width)
        Set the width (in units of 1/256th of a character width)

        The maximum column width for an individual cell is 255 characters. This value represents the number of characters that can be displayed in a cell that is formatted with the standard font (first font in the workbook).

        Character width is defined as the maximum digit width of the numbers 0, 1, 2, ... 9 as rendered using the default font (first font in the workbook).

        Unless you are using a very special font, the default character is '0' (zero), this is true for Arial (default font font in HSSF) and Calibri (default font in XSSF)

        Please note, that the width set by this method includes 4 pixels of margin padding (two on each side), plus 1 pixel padding for the gridlines (Section 3.3.1.12 of the OOXML spec). This results is a slightly less value of visible characters than passed to this method (approx. 1/2 of a character).

        To compute the actual number of visible characters, Excel uses the following formula (Section 3.3.1.12 of the OOXML spec):

        width = Truncate([{Number of Visible Characters} * {Maximum Digit Width} + {5 pixel padding}]/{Maximum Digit Width}*256)/256

        Using the Calibri font as an example, the maximum digit width of 11 point font size is 7 pixels (at 96 dpi). If you set a column width to be eight characters wide, e.g. setColumnWidth(columnIndex, 8*256), then the actual value of visible characters (the value shown in Excel) is derived from the following equation: Truncate([numChars*7+5]/7*256)/256 = 8;

        which gives 7.29.

        Specified by:
        setColumnWidth in interface Sheet
        Parameters:
        columnIndex - - the column to set (0-based)
        width - - the width in units of 1/256th of a character width
        Throws:
        IllegalArgumentException - if width > 255*256 (the maximum column width in Excel is 255 characters)

      • getColumnWidth

        public int getColumnWidth​(int columnIndex)

        columnIndex - - the column to set (0-based)
        Returns:

      • getColumnWidthInPixels

        public float getColumnWidthInPixels​(int column)

        Adds a merged region of cells (hence those cells form one). Skips validation. It is possible to create overlapping merged regions or create a merged region that intersects a multi-cell array formula with this formula, which may result in a corrupt workbook. To check for merged regions overlapping array formulas or other merged regions after addMergedRegionUnsafe has been called, call validateMergedRegions(), which runs in O(n^2) time.
        Specified by:
        addMergedRegionUnsafe in interface Sheet
        Parameters:
        region - to merge

        Specified by:
        validateMergedRegions in interface Sheet
        Throws:
        IllegalStateException - if region intersects with a multi-cell array formula
        IllegalStateException - if at least one region intersects with another merged region in this sheet

      • setForceFormulaRecalculation

        public void setForceFormulaRecalculation​(boolean value)
        Control if Excel should be asked to recalculate all formulas on this sheet when the workbook is opened.

        Calculating the formula values with FormulaEvaluator is the recommended solution, but this may be used for certain cases where evaluation in POI is not possible.

        It is recommended to force recalcuation of formulas on workbook level using Workbook.setForceFormulaRecalculation(boolean) to ensure that all cross-worksheet formuals and external dependencies are updated.

        Specified by:
        setForceFormulaRecalculation in interface Sheet
