public class ReferenceConfigSupplier<RefMessage extends PMessage<RefMessage>,ParentMessage extends PMessage<ParentMessage>>
extends UpdatingConfigSupplier<RefMessage>

A supplier to get a config (aka message) from a resource location. This is a fixed static supplier, so listening to changes will never do anything.

     ConfigSupplier<Service, Service._Field> supplier =
             new SerializedConfigSupplier<>(referencePath, Service.kDescriptor);

                               java.time.Clock clock,
                               PField... fieldRefs)
                        throws ConfigException

fieldRefs - Fields to reference.

Throws:

ConfigException - If message overriding failed
