Class ezcCacheStackStorageConfiguration

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.

Properties

float	read	`$freeRate` Fraction of $itemLimit that is freed if $storage runs full.
string	read	`$id` The unique ID of the configured storage in the stack.
int	read	`$itemLimit` Maximum number of items to be stored in $storage.
