memberSet method

@override bool memberSet(String varName, dynamic varValue, { String? from, bool isRecursive = true, bool throws = true, })

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 varName, dynamic varValue,
    {String? from, bool isRecursive = true, bool throws = true}) {
  final setter = '${InternalIdentifier.getter}$varName';

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

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

  if (throws) {
    throw HTError.undefined(varName);
  } else {
    return false;
  }
}
