- Field Detail
  - DEFAULT_WINDOW_SIZE
```
public static final int DEFAULT_WINDOW_SIZE
```
    Specifies how many rows can be accessed at most via getRow(). When a new node is created via createRow() and the total number of unflushed records would exeed the specified value, then the row with the lowest index value is flushed and cannot be accessed via getRow() anymore.

```
public SXSSFWorkbook()
```
    Construct a new workbook
  - SXSSFWorkbook
```
public SXSSFWorkbook(XSSFWorkbook workbook)
```
    Construct a workbook from a template.
    There are three use-cases to use SXSSFWorkbook(XSSFWorkbook) :
    1. Append new sheets to existing workbooks. You can open existing workbook from a file or create on the fly with XSSF.
    2. Append rows to existing sheets. The row number MUST be greater than max(rownum) in the template sheet.
    3. Use existing workbook as a template and re-use global objects such as cell styles, formats, images, etc.
    All three use cases can work in a combination.
    What is not supported:
    - Access initial cells and rows in the template. After constructing SXSSFWorkbook(XSSFWorkbook) all internal windows are empty and SXSSFSheet@getRow and SXSSFRow#getCell return null.
    - Override existing cells and rows. The API silently allows that but the output file is invalid and Excel cannot read it.
    Parameters:
    workbook - the template workbook
  - SXSSFWorkbook
```
public SXSSFWorkbook(XSSFWorkbook workbook,
             int rowAccessWindowSize)
```
    Constructs an workbook from an existing workbook.
    When a new node is created via createRow() and the total number of unflushed records would exceed the specified value, then the row with the lowest index value is flushed and cannot be accessed via getRow() anymore.
    
    A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.
    
    A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.
    
    Parameters:
    rowAccessWindowSize -
  - SXSSFWorkbook
```
public SXSSFWorkbook(XSSFWorkbook workbook,
             int rowAccessWindowSize,
             boolean compressTmpFiles)
```
    Constructs an workbook from an existing workbook.
    When a new node is created via createRow() and the total number of unflushed records would exceed the specified value, then the row with the lowest index value is flushed and cannot be accessed via getRow() anymore.
    
    A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.
    
    A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.
    
    Parameters:
    rowAccessWindowSize -
    compressTmpFiles - whether to use gzip compression for temporary files
  - SXSSFWorkbook
```
public SXSSFWorkbook(int rowAccessWindowSize)
```
    Construct an empty workbook and specify the window for row access.
    When a new node is created via createRow() and the total number of unflushed records would exceed the specified value, then the row with the lowest index value is flushed and cannot be accessed via getRow() anymore.
    
    A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.
    
    A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.
    
    Parameters:
    rowAccessWindowSize -
- Method Detail
  - getRandomAccessWindowSize
```
public int getRandomAccessWindowSize()
```
  - setCompressTempFiles
```
public void setCompressTempFiles(boolean compress)
```
    Set whether temp files should be compressed.
    SXSSF writes sheet data in temporary files (a temp file per-sheet) and the size of these temp files can grow to to a very large size, e.g. for a 20 MB csv data the size of the temp xml file become few GB large. If the "compress" flag is set to true then the temporary XML is gzipped.
    
    Please note the the "compress" option may cause performance penalty.
    
    Parameters:
    compress - whether to compress temp files
  - getXSSFWorkbook
```
public XSSFWorkbook getXSSFWorkbook()
```
  - getActiveSheetIndex
