Class PolymorphicMultimap<K,​V>

  • public class PolymorphicMultimap<K,​V>
extends Object
    A registry of objects by their class, along with all their parent classes and interfaces, up to and including an upper bound. The registry is highly concurrent, and performs registry lookups in O(1).

    • Method Detail

      • put

        public void put​(K key,
                V value)
        Puts an key to the registry along with an associated value. The key is registered under all classes and interfaces it extends and implements, up to and including the upper bound K.

        This implementation favors lookup speed at O(1), and pays the price during put(java.lang.Object, java.lang.Object).
