addEntries method
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<MapEntry<T, V>> entries) {
_notify(() {
super.addEntries(entries);
});
}
