## Property Details

$cache public property

Cache object or the application component ID of the cache object to be used.

After the CacheStateStorage object is created, if you want to change this property, you should only assign it with a cache object.

If not set - application 'cache' component will be used, but only, if it is available (e.g. in web application), otherwise - no cache will be used and no data saving will be performed.
