operator []= method
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) {
var current = _root;
// Navigate to the right node, create intermediaries as necessary.
for (final part in _getParts(key)) {
current = current.addChild(part);
}
// Increment the length only if no value existed before.
if (!current.hasKeyAndValue) {
_length++;
}
// Update key and value of the node.
current.setKeyAndValue(key, value);
}
