## Class BiMultiValMap<K,V>

- java.lang.Object
- - org.apache.cassandra.utils.BiMultiValMap<K,V>

- Type Parameters:
    `K` -
    `V` -
  All Implemented Interfaces:
    java.util.Map<K,V>
  Direct Known Subclasses:
    SortedBiMultiValMap

      public class BiMultiValMap<K,V>
      extends java.lang.Object
      implements java.util.Map<K,V>

  A variant of BiMap which does not enforce uniqueness of values. This means the inverse is a Multimap. (But the "forward" view is not a multimap; keys may only each have one value.)
