Class BiMap<T1,​T2>

  • All Implemented Interfaces:
    java.io.Serializable

    public class BiMap<T1,​T2>
    extends java.lang.Object
    implements java.io.Serializable
    BiMap is a bi-directional map. It is intended to hold items, T1 and T2, that have a 1-1 relationship and it is desired to look up item T2 from T1 and look up T1 from T2. If a new item is inserted that already exists in the map the add will fail

      • entrySet

        public java.util.Set<java.util.Map.Entry<T1,​T2>> entrySet()
        entrySet returns a Set of Entry objects from the bi-maps. It is intended to be used when iterating over the bi-maps. It works very similarly (same syntax) as the HashMap.entrySet(). However, the returned Set is independent of the contents of the bi-map. Thus, if you modify the returned Set, you will NOT modify the underlying bi-maps
