/**
 * Anyone using the {@link org.infinispan.AdvancedCache#addInterceptor(CommandInterceptor, int)} method (or any of its
 * overloaded forms) or registering custom interceptors via XML should extend this base class when creating their own 
 * custom interceptors.
 * <p />
 * As of Infinispan 5.1, annotations on custom interceptors, including {@link Inject}, {@link Start} and {@link Stop} 
 * will not be respected and callbacks will not be made.
 * <p />
 * Instead, custom interceptor authors should extend this base class to gain access to {@link Cache} and {@link EmbeddedCacheManager},
 * from which other components may be accessed.  Further, lifecycle should be implemented by overriding {@link #start()}
 * and {@link #stop()} as defined in this class.
