Class Method Summary collapse

Class Method Details

.expire(name, klass, relative = false) ⇒ Object

Expires (deletes) a cached page from the file system.

Input

  • relative = if set to true, prepends the controller mount path.

– FIXME: replace with ‘extend Nitro::Caching::Output’ ? this way we wont have to sync the same code in two different places. If you change this method, don’t forget the Caching::Output expire method.
