Examples with Empty com.google.protobuf.EmptyProtos.Empty used on opensource projects

Example 1 with Empty

use of com.google.protobuf.EmptyProtos.Empty in project grpc-java by grpc.

the class TlsTest method basicClientServerIntegrationTest.

/**
   * Tests that a client and a server configured using GrpcSslContexts can successfully
   * communicate with each other.
   */
@Test
public void basicClientServerIntegrationTest() throws Exception {
    // Create & start a server.
    File serverCertFile = TestUtils.loadCert("server1.pem");

    // Send an actual request, via the full GRPC & network stack, and check that a proper
    // response comes back.

}

Example 2 with Empty

use of com.google.protobuf.EmptyProtos.Empty in project grpc-java by grpc.

Example 3 with Empty

use of com.google.protobuf.EmptyProtos.Empty in project grpc-java by grpc.
