ClassDescriptionBiMap<K,
V> A simple bi-directional map.ConcurrentWeakMap<K,V> Concurrent weak hash map implementation.ISimpleList<T>Interface for a simple list abstraction.A simple container that can hold a value.The class represents a list which allows null elements, but doesn't allocate a memory for them, in the rest of cases it behaves like usualArrayList
and should have the same complexity (because keys are unique integers, so collisions are impossible).Portable implementation ofArrayList
.Tuple2<T1,T2> Simple tuple container that holds two elements.
