public abstract void delete(K key)
                     throws Exception

Deprecated.

Called when a mapping is removed from the cache. The removal was done by Cache.remove(K) or Cache.removeAll(). An expiry does not trigger a call to this method.

Throws:

Exception - if an exception occurs, the cache update will not occur and this exception will be wrapped in a CacheWriterException
