getValues() protected method Retrieves multiple values from cache with the specified keys. The default implementation calls getValue() multiple times to retrieve the cached values one by one. If the underlying cache storage supports multiget, this method should be overridden to exploit that feature. protected array getValues ( $keys )$keys array A list of keys identifying the cached values return array A list of cached values indexed by the keys

delete() public method Deletes a value with the specified key from cache public boolean delete ( $key )$key mixed A key identifying the value to be deleted from cache. This can be a simple string or a complex data structure consisting of factors representing the key. return boolean If no error happens during deletion

$keyPrefix public property A string prefixed to every cache key so that it is unique globally in the whole cache storage. It is recommended that you set a unique cache key prefix for each application if the same cache storage is being used by different applications. To ensure interoperability, only alphanumeric characters should be used. public string $keyPrefix = null

$dropDownCaret public property This property allows you to customize the HTML which is used to generate the drop down caret symbol, which is displayed next to the button text to indicate the drop down functionality. Defaults to null which means <span class="caret"></span> will be used. To disable the caret, set this property to be an empty string. public string $dropDownCaret = null

getDb() public static method Returns the database connection used by this AR class. By default, the "redis" application component is used as the database connection.
