Interface SerializedCacheValue<V>

public interface SerializedCacheValue<V>

Class SerializedCacheValue represents a serialized cache value. Instances of this class obtained from a region can be put into another region without a copy of this value being made. The two region entries will both have a reference to the same value.

If this value originated from a region stored off heap then this object can only be used as long as notification method that obtained it has not returned. For example if your implementation of CacheListener.afterUpdate(EntryEvent) obtains one by calling EntryEvent.getSerializedOldValue() then the SerializedCacheValue returned is only valid until your afterUpdate method returns. It is not safe to store instances of this class and use them later when using off heap storage.
