- * Modify a cache update operation array for EventRelayer::notify()

- * then the command involves setting a key to that value. Note that
- * for simplicity, 'val' is always a simple scalar value. This method
- * is used to possibly serialize the value and add any cache-specific
- * key/values needed for the relayer daemon (e.g. memcached flags).
