getParent<T> method
Gets the parent of the node identified by specified key.
Implementation
Node<T>? getParent<T>(String key, {Node? parent}) {
Node? _found;
List<Node> _children = parent == null ? this.children : parent.children;
Iterator iter = _children.iterator;
while (iter.moveNext()) {
Node child = iter.current;
if (child.key == key) {
_found = parent ?? child;
break;
} else {
if (child.isParent) {
_found = this.getParent<T>(key, parent: child);
if (_found != null) {
break;
}
}
}
}
return _found == null ? null : _found as Node<T>;
