T sort(int compare(T, T), [ bool iterator = true ])

Implementation

T sort(int Function(T, T) compare, [bool iterator = true]) {
  if (iterator) {
    return eachBefore((T node, b, c) {
      if (node.hasChild) {
        node._childrenList.sort(compare);
      }
      return false;
    });
  }
  _childrenList.sort(compare);
  return this as T;
}
