| |
| To get an instance of <code>CacheEntry</code> use <code>Cache.Entry.unwrap(Class)</code> method by passing |
| <code>CacheEntry</code> class to it as the argument. |
| <p> |
| <code>CacheEntry</code> is supported only for <code>Cache.Entry</code> returned by one of the following methods: |
| <ul> |
| <li><code>Cache.invoke(Object, EntryProcessor, Object...)</code></li> |
| <li><code>Cache.invokeAll(Set, EntryProcessor, Object...)</code></li> |

| </ul> |
| <p> |
| <code>CacheEntry</code> is not supported for <code>Cache.iterator()</code> because of performance reasons. |
| <code>Cache.iterator()</code> loads entries from all the cluster nodes and to speed up the load additional |
| information, like entry's version, is ignored. |
