Class BulkObjectPusher

java.lang.Object
  org.coffeecrew.mobile.oop.util.Observable
      org.coffeecrew.mobile.oop.impl.BulkObjectPusher

All Implemented Interfaces:

java.lang.Runnable, Observer

public class BulkObjectPusher
extends Observable
implements Observer, java.lang.Runnable

This class implements a mechanism to send multiple objects that are stored in a java.util.Vector to safely transfer them to a remote device. All the threading issues are covert within this class. You can also use ObjectPusher to transfer multiple objects to a remote device but then you have to synchronize the threads on your own.
BulkObjectPusher usage is like follows:

                // create your objects
                Person p = new Person();
                p.setName("Schneider");
                p.setVorname("Rosemarie");
                p.setAge(37);
                              
                Person hans = new Person();
                hans.setName("Peter");
                hans.setVorname("Hans");
                hans.setAge(37);
                
                //staff them into a vector
                Vector transferringObjects = new Vector();
                transferringObjects.addElement(p);
                transferringObjects.addElement(hans);
                
                //happy pushing
                new BulkObjectPusher(transferringObjects).addObserver(this);
