# updateAll method

void updateAll(

1. V update(
   1. K key,
   2. V value
   )

)
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

    void updateAll(V update(K key, V value)) {
      var root = _root;
      if (root == null) return;
      var iterator = _SplayTreeMapEntryIterator(this);
      while (iterator.moveNext()) {
        var node = iterator.current;
        var newValue = update(node.key, node.value);
        iterator._replaceValue(newValue);
      }
    }
