public delegate AsyncUnaryCall<TResponse> Interceptor.AsyncUnaryCallContinuation<TRequest, TResponse>(TRequest request, ClientInterceptorContext<TRequest, TResponse> context) where TRequest : class where TResponse : class
Represents a continuation for intercepting simple asynchronous invocations.
A delegate of this type is passed to the AsyncUnaryCall 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.
An instance of AsyncUnaryCall<TResponse>
representing an asynchronous invocation of a unary RPC.
The interceptor can choose to return the same object returned from
the continuation delegate or an arbitrarily constructed instance as it sees fit.
