      • addResponse

        public final T addResponse​(Address sender,
                                   Response response)
        Description copied from interface: ResponseCollector
        Called when a response is received, or when a target node becomes unavailable.

        When a target node leaves the cluster, this method is called with a CacheNotFoundResponse.

        Should return a non-null result if the request should complete, or null if it should wait for more responses. If the method throws an exception, the request will be completed with that exception. If the last response is received and addResponse() still returns null, ResponseCollector.finish() will also be called to obtain a result.

        Thread safety: addResponse() will *not* be called concurrently from multiple threads, and the request will not be completed while addResponse() is running.
