Multimaps

[Col-E]

Can possibly leverage delegating map to manage set/list backed multi-maps.

[Col-E]

Normal idea:

• SetMultiMap<K, Set<V>>
• ListMultiMap<K, List<V>>

Goofy idea:

• QueueMultiMap<K, Queue<V>>
  • Can have pollKey(K) to operate on queue associated with K
• StackMultiMap<K, Stack<V>>
  • Same idea, but with stacks.
