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.
