Find Type of Work Book

     

In this program we are going to find type of  workbook using POI3.0 API Event.

The methods used in this example:

 getSid():
This method is used to give the description  copied  from class.  

public static final short sid:
The sid variable is used for the less than operator as hex .

The public class BOFRecord extends Record class. It is  used for the beginning of a set of records that have a particular purpose or subject. Used in sheets and workbooks

getType():
This method is used to find type of object that is marked. This method returns short type of object.

The different types of: workbook are:
1.TYPE_WORKBOOK,
2. TYPE_VB_MODULE
3.TYPE_WORKSHEET
4.TYPE_CHART
5.TYPE_EXCEL_4_MACRO,
6.TYPE_WORKSPACE_FILE
In this example we are finding the type of workbook and compare it BOFRecord  .If compression returns true the print we are printing a String message . 

The code of the program is given below:
import java.io.*;
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.poifs.filesystem.*;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.eventusermodel.*;
import org.apache.poi.hssf.record.*;
import org.apache.poi.hssf.dev.EFHSSF;
public class TypeOfWorkBook implements HSSFListener

public static void main(String[] argsthrows IOException
  {  
  FileInputStream fin = new FileInputStream(args[0]);
  POIFSFileSystem poifs = new POIFSFileSystem(fin);
  InputStream din = poifs.createDocumentInputStream
(
"Workbook");
  HSSFRequest req = new HSSFRequest();
  req.addListenerForAllRecords(new TypeOfWorkBook());
  HSSFEventFactory factory = new HSSFEventFactory();
  factory.processEvents(req, din);
  fin.close();
  din.close();
  System.out.println("STOP");
  }
  public void processRecord(Record record)
  {
  switch (record.getSid())
  {
  case BOFRecord.sid:
  BOFRecord bof = (BOFRecordrecord;
  if (bof.getType() == bof.TYPE_WORKBOOK)
  {
  System.out.println("Encountered workbook");
  
  
  break;
  }
 }
  
}

The output of the program is given below:
