 DelegatingCacheCallback (CacheInterface::Callback *callback)
virtual bool ValidateCandidate (const GoogleString &key, CacheInterface::KeyState state)
virtual void Done (CacheInterface::KeyState state)

Detailed Description

Helper class for implementing Caches that wrap other caches, adding functionality in callbacks.


Member Function Documentation

This method is called once the cache implementation has found a match that was accepted by ValidateCandidate (in which case state == kAvailable) or it has failed to do so (state == kNotFound).

Implementations are free to invoke cache operations, as all cache locks are guaranteed to be released.

Implements net_instaweb::CacheInterface::Callback.

Note that we have to forward validity faithfully here, as if we're wrapping a 2-level cache it will need to know accurately if the value is valid or not.

Reimplemented from net_instaweb::CacheInterface::Callback.
