25 * Note: In situations where it would be awkward to subclass this
26 * class, the same affect can be achieved simply by implementing
27 * the {@link IAdaptable} interface and explicitly forwarding
28 * the <code>getAdapter</code> request to an implementation
29 * of the {@link IAdapterManager} service. The method would look like:
30 * <pre>
31 * public Object getAdapter(Class adapter) {
32 * IAdapterManager manager = ...;//lookup the IAdapterManager service
33 * return manager.getAdapter(this, adapter);
34 * }

37 * This class can be used without OSGi running.
