Header: Poco/UniqueExpireLRUCache.h
Description
A UniqueExpireLRUCache combines LRU caching and time based per entry expire caching. One can define for each cache entry a separate timepoint but also limit the size of the cache (per default: 1024). Each TValue object must thus offer the following method:
const Poco::Timestamp& getExpiration() const;
which returns the absolute timepoint when the entry will be invalidated. Accessing an object will NOT update this absolute expire timepoint. You can use the Poco::ExpirationDecorator to add the getExpiration method to values that do not have a getExpiration function.
