HSSFWorkbook (zss 3.8.0 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.

    Parameters:
    refIndex - Index to REF entry in EXTERNSHEET record in the Link Table
    definedNameIndex - zero-based to DEFINEDNAME or EXTERNALNAME record

  - 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

```
public int getNumberOfSheets()
```
    get the number of spreadsheets in the workbook (this will be three after serialization)
    
    Specified by:
    
    getNumberOfSheets in interface Workbook

```
    Get the HSSFSheet object at the given index.
    
    Specified by:
    
    getSheetAt in interface Workbook
    
    Parameters:
    index - of the sheet number (0-based physical & logical)
    
    Returns:
    HSSFSheet at the provided index
  - getSheet
```
public HSSFSheet getSheet(java.lang.String name)
```
    Get sheet with the given name (case insensitive match)
    
    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)
