Clears all elements from the cache. All memory of internal data structures will be freed but data of cache entries may stay in use, we do not call delete on any user data.

inlinevirtual |
Insert a new key-value pair to the list. If the cache is already full, the least recently used object is removed; afterwards the new object is inserted. If the object is already present it is updated and moved back to the end of the list
