title: serialize java objects of different classes into a single row in CSV using JSEFA
body: <p>I am using JSEFA to serialize my java object to into single row in CSV using JSEFA.
  I have arround 46 fields in one single class ,  </p>
  
  <p>But now the problem is i want to split this class into different sub classes which holds information,One class contains fields of CSV for first 23 positions and next class contains remaining position. When i tried approach of Prefix it is inserting data into two different rows but i need all data of two classes into a single row 
  can some body suggest best approach using JSEFA or any other .</p>
  
  <p>First class contains first two fields:</p>
  
  <pre><code>@CsvDataType(defaultPrefix = "1")
  
  public class TestClass1 implements Serializable {
  
  private static final long serialVersionUID = 371968159365574089L;
  
  @CsvField(pos = 1)
  private int id;
  
  @CsvField(pos = 2)
  private String Name;
  
  public int getId() {
      return this.id;
  }
  
  public void setId(final int id) {
      this.id = id;
  }
  
  public String getName() {
      return this.Name;
  }
  
  public void setName(final String name) {
      this.Name = name;
  }
    }
  </code></pre>
  
  <p>Sub Class 2 which contains remaining two fields:</p>
  
  <pre><code>@CsvDataType(defaultPrefix = "2")
   public class TestClass2 implements Serializable {
  
  private static final long serialVersionUID = 371968159365574089L;
  
  @CsvField(pos = 3)
  private int orderno;
  
  @CsvField(pos = 4)
  private String orderName;
  
  public int getOrderno() {
      return this.orderno;
  }
  
  public void setOrderno(final int orderno) {
      this.orderno = orderno;
  }
  
  
  public String getOrderName() {
      return orderName;
  }
  
  
  public void setOrderName(String orderName) {
      this.orderName = orderName;
  }
  
  
    }
  </code></pre>
  
  <p>main method for combining:</p>
  
  <pre><code> public static void main(final String[] args) {
  
  final File file = new File("/home/chandra/Documents/dataExcelFiles/final.csv");
      file.getParentFile().mkdirs();
   Serializer serializer = CsvIOFactory.createFactory(TestClass.class,  TestClass2.class).createSerializer();
  
      TestClass prod1 = new TestClass();
  
      prod1.setId(1);
      prod1.setName("HTC");
  
      TestClass2 prod2 = new TestClass2();
      prod2.setOrderno(512);
      prod2.setOrderName("HTC500");
  
      try {
  
          serializer.open(new FileWriter(file));
          serializer.write(prod1);
          serializer.write(prod2);
          serializer.close(true);
  
      } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
  }
  </code></pre>
  
  <p>Using this approach out put is like this :</p>
  
  <ul>
  <li>1 1      HTC      </li>
  <li>2 512 HTC500</li>
  </ul>
  
  <p>but i need out put every thing in one row  like this:</p>
  
  <ul>
  <li>1      HTC      512   HTC500</li>
  </ul>
  
  <p>Thanks,
  Chandra</p>
