K, V> typedef
Mixin implementing a Map.
This mixin has a basic implementation of all but five of the members of
Map class can be implemented by mixin in this class and
The remaining operations are implemented in terms of these five.
keys iterable should have efficient Iterable.length and
Iterable.contains operations, and it should catch concurrent modifications
of the keys while iterating.
A more efficient implementation is usually possible by overriding some of the other members as well.
// TODO: @Deprecated("Use MapBase instead") // Longer term: Deprecate `Map` unnamed constructor, to allow using `Map` // as skeleton class and replace `MapBase`. typedef MapMixin<K, V> = MapBase<K, V>;
