Description copied from interface: ServerInterceptor

Intercept ServerCall dispatch by the next ServerCallHandler. General semantics of ServerCallHandler.startCall(java.lang.String, io.grpc.ServerCall<ResponseT>, io.grpc.Metadata.Headers) apply and the returned ServerCall.Listener must not be null.

If the implementation throws an exception, call will be closed with an error. Implementations must not throw an exception if they started processing that may use call on another thread.

Specified by:

interceptCall in interface ServerInterceptor

Parameters:

method - fully qualified method name of the call

call - object to receive response messages

next - next processor in the interceptor chain

Returns:

listener for processing incoming messages for call, never null.
