| made. The two region entries will both have a reference to the same value. |
| <p> |
| 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 |
| <a href="../../../../org/apache/geode/cache/CacheListener.html#afterUpdate-org.apache.geode.cache.EntryEvent-"><code>CacheListener.afterUpdate(EntryEvent)</code></a> obtains one by calling |
| <a href="../../../../org/apache/geode/cache/EntryEvent.html#getSerializedOldValue--"><code>EntryEvent.getSerializedOldValue()</code></a> 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. Attempts to access off-heap data from this event after it |
| has expired will result in an IllegalStateException.</div> |
