Class GrpcClientRequest<Req,Resp>

java.lang.Object

io.vertx.reactivex.grpc.common.GrpcWriteStream<Req>

io.vertx.reactivex.grpc.client.GrpcClientRequest<Req,Resp>

All Implemented Interfaces:

StreamBase, WriteStream<Req>

public class GrpcClientRequest<Req,Resp>
extends GrpcWriteStream<Req>

A request to a gRPC server.

You interact with the remote service with gRPC generated messages or protobuf encoded messages.

Before sending a request you need to set #serviceName) and #methodName) or alternatively the service fullMethodName(java.lang.String).

Writing a request message will send the request to the service:

• To send a unary request, just call
• To send a streaming request, call any time you need and then WriteStream.end(io.vertx.core.Handler<io.vertx.core.AsyncResult<java.lang.Void>>)

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
