public interface Adaptable

Adaptable objects lets you add interfaces to a class and lets clients query whether an object has a particular extension. This means adaptable objects can be dynamically extended. Adapters are created by adapter factories, which are registered with an global adapter manager.

     Adaptable a = ...;
     MyExtension x = a.getAdapter( MyExtension.class );
     if( x != null ) {
       // invoke MyExtension methods on x ...
     }
