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

A mutable MultiMap builder used to efficiently create new immutable instances. See the MultiMap documentation and the MultiMap.Builder API documentation

A context instance for MultiMap implementations that acts as a factory for every instance of this type of collection.

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

Utility interface that provides higher-kinded types for this collection.
