/**
* 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.
*
* 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.
*
* 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.
*
* @author Manik Surtani
* @deprecated Since 9.0, use {@link BaseCustomAsyncInterceptor} instead.
