Class Wrapper<E>

java.lang.Object
  edu.ksu.cis.projects.bogor.util.Wrapper<E>

public final class Wrapper<E>
extends Object

Convenience class used to host a re-assignable reference. This is useful primarily when one wants to update a local variable from within an anonymous class's method body. E.g.,

 public void foo() throws InterruptedException
 {
     final Wrapper<String> wr = new Wrapper<String>("foo");
     Thread t = new Thread(new Runnable()
         {
             public void run()
             {
                 wr.element = "bar";
             }
         });
     t.start();
     t.join();
 }
