TTMultiMapList<V> class
Return a TTMultiMap that stores values in a List
Returned TTMultiMap is a function:
- f : K ↦ Vℕ ∪ V∅
such that
- K is the set of all Keys
- V is the set of all Values
- ℕ is the set of Natural numbers
- Vℕ is the set of all functions ℕ ↦ V
- V∅ contains the empty function ∅ ↦ V
By definition the Values sequence may feature the same Value multiple times. It is ordered by insertion.
The codomain of f includes the empty sequence. This allows Keys to be stored without Values, useful when you require only a set of Keys for searching purposes.
