end

end

#cache_key_matcher ⇒ Object

Returns the type of key matcher supported by the cache store. Note that the type returned here may not be accurate for cache stores that don’t support matchers at all. For those cases, you should still expect NotImplemented exceptions to be thrown when calling cache_expire_by_pattern.
