`interface HashMultiMapHashValue.NonEmpty<K,V>`

A non-empty type-invariant immutable MultiMap of key type K, and value type V. In the MultiMap, each key has at least one value. See the MultiMap documentation and the HashMultiMapHashValue API documentation

Extends: Streamable.NonEmpty<T>, HashMultiMapHashValue<K,V>

Type parameters

Name	Description
K	the key type
V	the value type

note

The HashMultiMapHashValue uses the contexts' HashMap keyContext to hash the keys - The HashMultiMapHashValue uses the contexts' HashSet valueContext to collect the values for each key.

example

const m1 = HashMultiMapHashValue.empty<number, string>()
const m2 = HashMultiMapHashValue.of([1, 'a'], [1, 'b'], [2, 'a'])

undocumented

stream(): Stream.NonEmpty<[K, V]>;
