java.lang.Object com.tangosol.util.Base com.tangosol.coherence.servlet.AbstractHttpSessionModel com.tangosol.coherence.servlet.MonolithicHttpSessionModel
public class MonolithicHttpSessionModel
This is an implementation of HttpSessionModel that manages its attribute state in a single ('monolithic') serializable unit, allowing session attributes to safely form graphs while avoiding duplication of objects, yet not being able to optimize attribute serialization and deserialization as a result.
Note that the Externalizable implementation on this class is just there to throw exceptions that this class is not Serializable or Externalizable. Use ExternalizableLite instead.
