Method Detail

setExtensionRegistry

@ExperimentalApi(value="https://github.com/grpc/grpc-java/issues/1787")
public static void setExtensionRegistry(ExtensionRegistryLite newRegistry)

Sets the global registry for proto marshalling shared across all servers and clients.

Warning: This API will likely change over time. It is not possible to have separate registries per Process, Server, Channel, Service, or Method. This is intentional until there is a more appropriate API to set them.

Warning: Do NOT modify the extension registry after setting it. It is thread safe to call setExtensionRegistry(com.google.protobuf.ExtensionRegistryLite), but not to modify the underlying object.

If you need custom parsing behavior for protos, you will need to make your own MethodDescriptor.Marshaller for the time being.
