Interface MarshalledEntry<K,V>

All Known Implementing Classes:

MarshalledEntryImpl

public interface MarshalledEntry<K,V>

Defines an externally persisted entry. External stores that keep the data in serialised form should return an MarshalledEntry that contains the data in binary form (ByteBuffer) and unmarshall it lazily when getKey/Value/Metadata are invoked. This approach avoids unnecessary object (de)serialization e.g when the entries are fetched from the external store for the sole purpose of being sent over the wire to another requestor node.
