addEntries method

  1. @override
void addEntries(
  1. Iterable<Object> entries
)
override

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

If a key of newEntries is already in this map, the corresponding value is overwritten.

The operation is equivalent to doing this[entry.key] = entry.value for each MapEntry of the iterable.

final planets = <int, String>{1: 'Mercury', 2: 'Venus',
  3: 'Earth', 4: 'Mars'};
final gasGiants = <int, String>{5: 'Jupiter', 6: 'Saturn'};
final iceGiants = <int, String>{7: 'Uranus', 8: 'Neptune'};
planets.addEntries(gasGiants.entries);
planets.addEntries(iceGiants.entries);
print(planets);
// {1: Mercury, 2: Venus, 3: Earth, 4: Mars, 5: Jupiter, 6: Saturn,
//  7: Uranus, 8: Neptune}

Implementation

@override
void addEntries(Iterable<Object> entries) {
  // TODO(cbracken): Dart 2.0 requires this method to be implemented.
  // Change Iterable<Object> to Iterable<MapEntry<K, V>> when
  // the MapEntry class has been added.
  throw UnimplementedError('addEntries');
