Class ezcCacheStackStorageConfiguration


Configuration for a ezcCacheStackableStorage inside an ezcCacheStack. The configuration consists of a string $id that identifies the $storage uniquely inside the stack. The $itemLimit is the maximum number of items that might be stored in the $storage at once. This number is determined by the used ezcCacheStackMetaData used in the stack. The $freeRate is the fraction of $itemLimit that will be freed by the used ezcCacheStackReplacementStrategy when the storage runs full.
