        Description copied from class: io.helidon.microprofile.grpc.core.AbstractMethodHandlerSupplier.AbstractHandler
        Invoke the actual unary or server streaming gRPC method handler.
        Specified by:
        invoke in class io.helidon.microprofile.grpc.core.AbstractMethodHandlerSupplier.AbstractHandler<ReqT,​RespT>
        Parameters:
        method - the Method to invoke
        instance - the service instance to invoke the method on
        request - the method request
        observer - the method response observer
        Throws:
        InvocationTargetException - if an error occurs invoking the method
        IllegalAccessException - if the method cannot be accessed
      • unary

        public Object unary​(Object[] args,
                            MethodHandler.UnaryClient client)
        Invoke the client call.

        The call is from a method signature:

             RestT invoke(ReqT request);
         
        so the request is in args[0].
        Parameters:
        args - the call arguments.
        client - the MethodHandler.UnaryClient instance to forward the call to
        Returns:
        the request response
