memberSet method

@override bool memberSet(String id, dynamic value, { String? from, bool isRecursive = true, bool ignoreUndefined = false, bool defineIfAbsent = false, })

HTInstanceNamespace overrided HTNamespace's memberSet, with a new named parameter isRecursive. If isRecursive is false, then it won't continue to try assigning variable from enclosed namespace.

Implementation

@override
bool memberSet(
  String id,
  dynamic value, {
  String? from,
  bool isRecursive = true,
  bool ignoreUndefined = false,
  bool defineIfAbsent = false,
}) {
  final setter = '${InternalIdentifier.getter}$id';

  if (isRecursive) {
    HTInstanceNamespace? curNamespace = runtimeInstanceNamespace;
    while (curNamespace != null) {
      if (curNamespace.symbols.containsKey(id) ||
          curNamespace.symbols.containsKey(setter)) {
        instance.memberSet(id, value, from: from, cast: curNamespace.classId);
        return true;
      } else {
        curNamespace = curNamespace.next;
      }
    }
  } else {
    if (symbols.containsKey(id) || symbols.containsKey(setter)) {
      instance.memberSet(id, value, from: from, cast: classId);
      return true;
    }
  }

  if (isRecursive && closure != null) {
    return closure!.memberSet(id, value, from: from);
  }

  if (!ignoreUndefined) {
    throw HTError.undefined(id);
  } else {
    return false;
  }
}
