Class MarshalledValue

java.lang.Object

org.jboss.cache.marshall.MarshalledValue

All Implemented Interfaces:

Externalizable, Serializable

public class MarshalledValue
extends Object
implements Externalizable

The MarshalledValueInterceptor handles transparent wrapping/unwrapping of cached data.

Since:

MarshalledValue

public MarshalledValue(Object instance)
                throws NotSerializableException

Throws:

NotSerializableException

MarshalledValue

public MarshalledValue()

Method Detail

setEqualityPreferenceForInstance

public void setEqualityPreferenceForInstance(boolean equalityPreferenceForInstance)

serialize

public void serialize()

deserialize

public void deserialize()

compact

public void compact(boolean preferSerializedRepresentation,
           boolean force)

Compacts the references held by this class to a single reference. If only one representation exists this method is a no-op unless the 'force' parameter is used, in which case the reference held is forcefully switched to the 'preferred representation'.

Either way, a call to compact() will ensure that only one representation is held.

Parameters:

preferSerializedRepresentation - if true and both representations exist, the serialized representation is favoured. If false, the deserialized representation is preferred.

force - ensures the preferred representation is maintained and the other released, even if this means serializing or deserializing.
