# addEntries abstract method

void addEntries(

1. Iterable<MapEntry<K, V>> newEntries

)

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

    void addEntries(Iterable<MapEntry<K, V>> newEntries);
