wp_get_cache_type() WP-CLI 1.0

Attempts to determine which object cache is being used.

Note that the guesses made by this function are based on the WP_Object_Cache classes that define the 3rd party object cache extension. Changes to those classes could render problems with this function's ability to determine which object cache is being used.

Хуков нет.
