operator []= method

@override void operator []=(K key, V value)

Associates the key with the given value.

If the key was already in the map, its associated value is changed. Otherwise the key/value pair is added to the map.

Implementation

@override
void operator []=(K key, V value) {
  if (_data.containsKey(key) && valueEquality.equals(_data[key], value)) return;
  _data[key] = value;
  invalidate();
}
