Class MarshallableObject<T>

java.lang.Object
org.infinispan.marshall.protostream.impl.MarshallableObject<T>
@ProtoTypeId(22) public class MarshallableObject<T> extends Object
A wrapper for interface implementations which can either be marshalled by the GlobalMarshaller or the configured user marshaller if no internal marshaller exists for the implementation. In such scenarios it's not possible to use WrappedMessage as it will ignore any configured user marshaller, and similarly, it's not possible to use MarshallableUserObject as that exclusively utilises the user marshaller.

A good example of when this class is required, is for the marshalling of Metadata implementations. We utilise many internal implementations, which always have a ProtoStream marshaller available; however, it's also possible for users to provide custom implementations which must be handled by the configured user marshaller.
