SplayTreeMap<K, V>.from constructor

SplayTreeMap<K, V>.from(Map other, [ int compare(K key1 K key2), bool isValidKey(dynamic potentialKey) ])

Creates a SplayTreeMap that contains all key/value pairs of other.

The keys must all be instances of K and the values of V. The other map itself can have any type.

Implementation

factory SplayTreeMap.from(Map<dynamic, dynamic> other,
    [int Function(K key1, K key2)? compare,
    bool Function(dynamic potentialKey)? isValidKey]) {
  if (other is Map<K, V>) {
    return SplayTreeMap<K, V>.of(other, compare, isValidKey);
  }
  SplayTreeMap<K, V> result = SplayTreeMap<K, V>(compare, isValidKey);
  other.forEach((dynamic k, dynamic v) {
    result[k] = v;
  });
  return result;
}
