Class ClassMetaCache<T>

  • Type Parameters:
    T - type of objects stored in cache

    public class ClassMetaCache<T>
    extends Object
    This class wraps a WeakHashMap that holds one ConcurrentHashMap per ClassLoader. In the rare event of a previously unmapped ClassLoader, the WeakHashMap is replaced by a new one. This avoids any synchronization overhead, much like a CopyOnWriteArrayList
