Class Horde_Kolab_Storage_Cache

The Kolab_Cache class provides a cache for Kolab groupware objects.

The Horde_Kolab_Storage_Cache singleton instance provides caching for all storage folders. So before operating on the cache data it is necessary to load the desired folder data. Before switching the folder the cache data should be saved.

This class does not offer a lot of safeties and is primarily intended to be used within the Horde_Kolab_Storage_Data class.
