Class HSSFWorkbook

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, Workbook

    public final class HSSFWorkbook
extends POIDocument
implements Workbook
    High level representation of a workbook. This is the first object most users will construct whether they are reading or writing a workbook. It is also the top level object for creating new sheets/etc.
    See Also:
    InternalWorkbook, HSSFSheet

    • Field Detail

      • INITIAL_CAPACITY

        public static final int INITIAL_CAPACITY
        used for compile-time performance/memory optimization. This determines the initial capacity for the sheet collection. Its currently set to 3. Changing it in this release will decrease performance since you're never allowed to have more or less than three sheets!

    • Constructor Detail

      • HSSFWorkbook

        public HSSFWorkbook()
        Creates new HSSFWorkbook from scratch (start here!)

      • HSSFWorkbook

        public HSSFWorkbook(POIFSFileSystem fs,
                    boolean preserveNodes)
             throws java.io.IOException
        Given a POI POIFSFileSystem object, read in its Workbook and populate the high and low level models. If you're reading in a workbook... start here!
        Parameters:
        fs - the POI filesystem that contains the Workbook stream.
        preserveNodes - whether to preserve other nodes, such as macros. This takes more memory, so only say yes if you need to. If set, will store all of the POIFSFileSystem in memory
        Throws:
        java.io.IOException - if the stream cannot be read
        See Also:

             throws java.io.IOException
        given a POI POIFSFileSystem object, and a specific directory within it, read in its Workbook and populate the high and low level models. If you're reading in a workbook...start here.

      • findSheetNameFromExternSheet

        @Deprecated

      • createSheet

        public HSSFSheet createSheet()
        create an HSSFSheet for this HSSFWorkbook, adds it to the sheets and returns the high level representation. Use this to create new sheets.
        Specified by:
        createSheet in interface Workbook
        Returns:
        HSSFSheet representing the new sheet.

      • cloneSheet

        public HSSFSheet cloneSheet(int sheetIndex)
        create an HSSFSheet from an existing sheet in the HSSFWorkbook.
        Specified by:
        cloneSheet in interface Workbook
        Returns:
        HSSFSheet representing the cloned sheet.

      • createSheet

        public HSSFSheet createSheet(java.lang.String sheetname)
        Create a new sheet for this Workbook and return the high level representation. Use this to create new sheets.

        Note that Excel allows sheet names up to 31 chars in length but other applications (such as OpenOffice) allow more. Some versions of Excel crash with names longer than 31 chars, others - truncate such names to 31 character.

        POI's SpreadsheetAPI silently truncates the input argument to 31 characters. Example: 

        
     Sheet sheet = workbook.createSheet("My very long sheet name which is longer than 31 chars"); // will be truncated
     assert 31 == sheet.getSheetName().length();
     assert "My very long sheet name which i" == sheet.getSheetName();

        Except the 31-character constraint, Excel applies some other rules:

        Sheet name MUST be unique in the workbook and MUST NOT contain the any of the following characters:

        • 0x0000
        • 0x0003
        • colon (:)
        • backslash (\)
        • asterisk (*)
        • question mark (?)
        • forward slash (/)
        • opening square bracket ([)
        • closing square bracket (])
        The string MUST NOT begin or end with the single quote (') character.

        Specified by:
        createSheet in interface Workbook
        Parameters:
        sheetname - sheetname to set for the sheet.
        Returns:
        Sheet representing the new sheet.
        Throws:
        java.lang.IllegalArgumentException - if the name is null or invalid or workbook already contains a sheet with this name
        See Also:
        WorkbookUtil.createSafeSheetName(String nameProposal)

      • getNumberOfSheets

        public int getNumberOfSheets()

        @Deprecated
public int getSheetIndexFromExternSheetIndex(int externSheetNumber)

      • getSheetAt

        public HSSFSheet getSheetAt(int index)

        Specified by:
        getSheet in interface Workbook
        Parameters:
        name - of the sheet
        Returns:
        HSSFSheet with the name provided or null if it does not exist

      • removeSheetAt

        public void removeSheetAt(int index)
        Removes sheet at the given index.

        Care must be taken if the removed sheet is the currently active or only selected sheet in the workbook. There are a few situations when Excel must have a selection and/or active sheet. (For example when printing - see Bug 40414).
        This method makes sure that if the removed sheet was active, another sheet will become active in its place. Furthermore, if the removed sheet was the only selected sheet, another sheet will become selected. The newly active/selected sheet will have the same index, or one less if the removed sheet was the last in the workbook.

        Specified by:
        removeSheetAt in interface Workbook
        Parameters:
        index - of the sheet (0-based)

        Whether the application shall perform a full recalculation when the workbook is opened.

        Typically you want to force formula recalculation when you modify cell formulas or values of a workbook previously created by Excel. When set to true, this flag will tell Excel that it needs to recalculate all formulas in the workbook the next time the file is opened.

        Note, that recalculation updates cached formula results and, thus, modifies the workbook. Depending on the version, Excel may prompt you with "Do you want to save the changes in filename?" on close.

        Specified by:
        setForceFormulaRecalculation in interface Workbook

        value - true if the application will perform a full recalculation of workbook values when the workbook is opened

        Changes an external referenced file to another file. A formula in Excel which references a cell in another file is saved in two parts: The referenced file is stored in an reference table. the row/cell information is saved separate. This method invocation will only change the reference in the lookup-table itself.
        Parameters:
        oldUrl - The old URL to search for and which is to be replaced
        newUrl - The URL replacement
        Returns:
