<p>The interceptor manager object retains reference to the next and previous interceptor object in the interceptor chain, and forward corresponding events to them.</p>
<p>All methods except the initializer of the class can only be called on the manager's dispatch queue. Since the manager's dispatch queue targets corresponding interceptor's dispatch queue, it is also safe to call the manager's methods in the corresponding interceptor instance's methods that implement <a class="el" href="protocol_g_r_p_c_interceptor_interface-p.html" title="The GRPCInterceptorInterface defines the request events that can occur to an interceptor.">GRPCInterceptorInterface</a>.</p>
<p>When an interceptor is shutting down, it must invoke -shutDown method of its corresponding manager so that references to other interceptors can be released and proper clean-up is made. </p>
