    )
)
override

Updates all values.

Iterates over all entries in the map and updates them with the result of invoking update.

final terrestrial = <int, String>{1: 'Mercury', 2: 'Venus', 3: 'Earth'};
terrestrial.updateAll((key, value) => value.toUpperCase());
print(terrestrial); // {1: MERCURY, 2: VENUS, 3: EARTH}

Implementation

@override
void updateAll(V update(K key, V value)) {
  for (var key in keys.toList()) {
    final k = _keySerializer(key);
    final v = update(key, _valueDeserializer(_dbm.get(k)!));
    _dbm.put(_keySerializer(key), _valueSerializer(v));
  }
}
