HSSFWorkbook (zss 3.9.3 API)

java.lang.Object
- org.zkoss.poi.POIDocument
- - org.zkoss.poi.hssf.usermodel.HSSFWorkbook

All Implemented Interfaces:

Workbook
```
public 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.

`HSSFWorkbook(DirectoryNode directory, POIFSFileSystem fs, boolean preserveNodes)` given a POI POIFSFileSystem object, and a specific directory within it, read in its Workbook and populate the high and low level models.
`HSSFWorkbook(java.io.InputStream s)`
`HSSFWorkbook(java.io.InputStream s, boolean preserveNodes)` Companion to HSSFWorkbook(POIFSFileSystem), this constructs the POI filesystem around your inputstream.
`HSSFWorkbook(POIFSFileSystem fs)`

  - 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

  - 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)
