All Known Subinterfaces:

MarshalledEntry<K,V>
```
public interface MarshallableEntry<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.

- Method Detail
  - getKeyBytes
```
ByteBuffer getKeyBytes()
```
    Returns the key in serialized format.
  - getValueBytes
```
ByteBuffer getValueBytes()
```
    Returns the value in serialize format.
  - getMetadataBytes
```
ByteBuffer getMetadataBytes()
```
    Returns:
    
    null if there's no metadata associated with the object (e.g. expiry info, version..)
  - getKey
```
K getKey()
```
    Returns the same key as getKeyBytes(), but unmarshalled.
  - getValue
```
V getValue()
```
    Returns the same value as getKeyBytes(), but unmarshalled.
  - getMetadata
```
Metadata getMetadata()
```
    Returns:
    
    might be null if there's no metadata associated with the object (e.g. expiry info, version..).
  - created
```
long created()
```
  - lastUsed
```
long lastUsed()
```
  - isExpired
```
boolean isExpired(long now)
```
  - expiryTime
```
long expiryTime()
```
  - asMarshalledEntry
```
@Deprecated
default MarshalledEntry<K,V> asMarshalledEntry()
```
    Deprecated.
    This should not be used by users and will be removed in subsequent versions along with MarshalledEntry.
    
    A bridge method required to ensure backwards compatibility with old store implementations that rely on MarshalledEntry. It's not possible to simply create a static wrapper class around a MarshallableEntry as getMetadataBytes() is different from getMetadataBytes() and we require a Marshaller instance to generate said bytes.
  - getMarshalledValue
```
MarshalledValue getMarshalledValue()
```
