Prado\Caching\TCache::getValue PHP Méthode

getValue() abstract protected méthode

This method should be implemented by child classes to store the data in specific cache storage. The uniqueness and dependency are handled in {@link get()} already. So only the implementation of data retrieval is needed.

abstract protected getValue ( $key ) : string
Résultat	string	the value stored in cache, false if the value is not in the cache or expired.
