addAll method

void addAll (Map<K, V> other)
override

Adds all key/value pairs of other to this map.

If a key of other is already in this map, its value is overwritten.

The operation is equivalent to doing this[key] = value for each key and associated value in other. It iterates over other, which must therefore not change during the iteration.

Implementation

void addAll(Map<K, V> other) {
  _map.addAll(other);
}
