public static interface CacheMarshaller.ValidationPolicy
Validation policies are responsible for computing whether or not a cached data structure is valid for the current context.

getValidCachedData(getCacheableData(o), conf) should return an object equivalent to o in the expected case.

Implementations of this class will often also implement Configurable in order to receive the current Configuration.
