public delegate AsyncDuplexStreamingCall<TRequest, TResponse> AsyncDuplexStreamingCallContinuation<TRequest, TResponse>(ClientInterceptorContext<TRequest, TResponse> context) where TRequest : class where TResponse : class;
Represents a continuation for intercepting asynchronous duplex invocations. A delegate of this type is passed to the AsyncDuplexStreamingCall method when an outgoing invocation is being intercepted and calling the delegate will invoke the next interceptor in the chain, or the underlying call invoker if called from the last interceptor. The interceptor is allowed to call it zero, one, or multiple times, passing it the appropriate request value and context as it sees fit.
The ClientInterceptorContext<TRequest, TResponse> instance to pass to the next step in the invocation process.
An instance of AsyncDuplexStreamingCall<TRequest, TResponse> representing an asynchronous invocation of a duplex-streaming RPC. The interceptor can choose to return the same object returned from the continuation delegate or an arbitrarily constructed instance as it sees fit.
