Class NonSerializingCacheWrapper<T>

java.lang.Object
  com.bea.netuix.application.util.NonSerializingCacheWrapper<T>

All Implemented Interfaces

Externalizable, Serializable

public class NonSerializingCacheWrapper<T>
extends Object
implements Externalizable

The NonSerializingCacheWrapper object wraps a cache and ensures it is not serialized. This is useful when storing a cache in an HttpSession and the cache is not intended to be replicated (if session replication is being used). This allows the cache to gain all the benefits of being in a Session object (namely, a lifespan equal to the Session lifespan) but without incurring any burden on the session replication mechanism.
