All Implemented Interfaces:
Closeable, AutoCloseable, Iterable<Sheet>, Workbook

public final class HSSFWorkbook extends POIDocument implements Workbook

  • Field Details

    • 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!
    • _sheets

      protected List<HSSFSheet> _sheets
      this holds the HSSFSheet objects attached to this workbook
  • Constructor Details

    • 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.

      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(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.

      Parameters:
      sheetname - sheetname to set for the sheet.
      Returns:
      Sheet representing the new sheet.
      Throws:
      IllegalArgumentException - if the name is null or invalid or workbook already contains a sheet with this name

    • 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.
