      public final class HashMap5<K1,​K2,​K3,​K4,​K5,​V>
      extends java.util.HashMap<MapKey5<K1,​K2,​K3,​K4,​K5>,​V>

  A 5-dimensional hash map. Instances of this class map tuples with 5 elements to value and provide some convenience functions to access elements without having to explicitly construct the tuples. Tuples are mapped using their hash codes.
