LruCacheSingleton class
A singleton class that manages both in-memory and disk-based LRU caches.
This class provides a unified interface for caching binary data in memory and files on disk. It ensures thread safety and lazy initialization for the storage cache. The cache sizes are configurable via the Config class.
Constructors
- LruCacheSingleton.new()
-
