Detailed Description

Cacheable object.

This interface can be implemented by any class that is going to be passed into a cache and allows it to take control of the structure and the information about to be cached, as well as how to deal with it when it is retrieved from a cache. Think of it like serialisation and the __sleep and __wakeup methods. This is used because cache stores are responsible for how they interact with data and what they do when storing it. This interface ensures there is always a guaranteed action.
