Method Details

of

static GrpcJsonMarshaller of(ServiceDescriptor serviceDescriptor)

Returns a newly-created GrpcJsonMarshaller which serializes and deserializes a Message served by the service. This implementation internally uses protobuf-jackson to serialize and deserialize messages.

builder

static GrpcJsonMarshallerBuilder builder()

Returns a new GrpcJsonMarshallerBuilder. This implementation internally uses protobuf-jackson to serialize and deserialize messages.

ofGson

static GrpcJsonMarshaller ofGson()

Returns a newly-created GrpcJsonMarshaller which serializes and deserializes a Message. This implementation internally uses JsonFormat and Gson to serialize and deserialize messages. Note: JsonFormat has a known performance issue. Use this method only when 1) you're using Protobuf 2 or 2) you have an issue with protobuf-jackson.

builderForGson

static GsonGrpcJsonMarshallerBuilder builderForGson()

Returns a new GsonGrpcJsonMarshallerBuilder. This implementation internally uses JsonFormat and Gson to serialize and deserialize messages. Note: JsonFormat has a known performance issue. Use this method only when 1) you're using Protobuf 2 or 2) you have an issue with protobuf-jackson.
