__call ( string $name, array $arguments ) : mixed	Redirects calls to original datasource methods. Needed if the Cacher.Cache behavior is attached before other behaviors that use the model's datasource methods.
__construct ( array $config = [] )	Constructor
clearModelCache ( Model $Model, $query = null )	* Clears the cache for a specific model and rewrites the map. Pass query to clear a specific query's cached results
describe ( mixed $model ) : mixed	Since Datasource has the method describe(), it won't be caught __call().
read ( Model $Model, array $queryData = [], integer $recursive = null ) : array	Reads from cache if it exists. If not, it falls back to the original datasource to retrieve the data and cache it for later
