io.vertx.grpc.server

Interface GrpcServer

All Superinterfaces:

Handler<HttpServerRequest>

public interface GrpcServer
extends Handler<HttpServerRequest>

A gRPC server based on Vert.x HTTP server.

The server can be used as a HttpServer handler or mounted as a Vert.x Web handler.

Unlike traditional gRPC servers, this server does not rely on a generated RPC interface to interact with the service. Instead, you can interact with the service with a request/response interfaces and gRPC messages, very much like a traditional client. The server exposes 2 levels of handlers

• a Protobuf message handler: GrpcServerRequest/GrpcServerResponse with Protobuf message that handles any method call in a generic way
• a gRPC message handler: GrpcServerRequest/GrpcServerRequest with gRPC messages that handles specific service method calls

Method Summary

Modifier and Type	Method and Description
GrpcServer	callHandler(Handler<GrpcServerRequest<Buffer,Buffer>> handler) Set a call handler that handles any call made to the server.
<Req,Resp> GrpcServer	callHandler(io.grpc.MethodDescriptor<Req,Resp> methodDesc, Handler<GrpcServerRequest<Req,Resp>> handler) Set a service method call handler that handles any call call made to the server for the MethodDescriptor service method.
static GrpcServer	server(Vertx vertx) Create a blank gRPC server
