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 other,
    [int compare(K key1, K key2), bool isValidKey(potentialKey)]) {
  SplayTreeMap<K, V> result = SplayTreeMap<K, V>(compare, isValidKey);
  other.forEach((k, v) {
    result[k] = v;
  });
  return result;
}
