    • Field Detail

      • objects

        protected java.util.Map objects
        The map for (value -> objects).

      • tuples

        protected java.util.Map tuples
        The map for (value -> tuples).

      • ovalues

        protected java.util.Map ovalues
        The cached values (object -> value). Required, because objects can change and old value (for removal) can no longer be obtained.

      • tvalues

        protected java.util.Map tvalues
        The cached values (tuple -> value). Required, because objects can change and old value (for removal) can no longer be obtained.
