PHP Класс Prado\Caching\TCache

TCache is the base class for cache classes with different cache storage implementation. TCache implements the interface {@link ICache} with the following methods, - {@link get} : retrieve the value with a key (if any) from cache - {@link set} : store the value with a key into cache - {@link add} : store the value only if cache does not have this key - {@link delete} : delete the value with the specified key from cache - {@link flush} : delete all values from cache Each value is associated with an expiration time. The {@link get} operation ensures that any expired value will not be returned. The expiration time by the number of seconds. A expiration time 0 represents never expire. By definition, cache does not ensure the existence of a value even if it never expires. Cache is not meant to be an persistent storage. Child classes must implement the following methods: - {@link getValue} - {@link setValue} - {@link addValue} - {@link deleteValue} and optionally {@link flush} Since version 3.1.2, TCache implements the \ArrayAccess interface such that the cache acts as an array.
