memberSet method

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

Fetch a declaration from this namespace, if not found and isRecursive is true, will continue search in super namespaces, then assign the value to that declaration. If isRecursive is true, means this is not a 'memberset operator' search.

Implementation

@override
bool memberSet(
  String varName,
  dynamic varValue, {
  String? from,
  bool isRecursive = true,
  bool throws = true,
}) {
  final setter = '${InternalIdentifier.setter}$varName';
  if (symbols.containsKey(varName)) {
    final decl = symbols[varName]!;
    if (decl.isPrivate && from != null && !from.startsWith(fullName)) {
      throw HTError.privateMember(varName);
    }
    decl.resolve();
    decl.value = varValue;
    return true;
  } else if (symbols.containsKey(setter)) {
    final decl = symbols[setter]!;
    if (decl.isPrivate && from != null && !from.startsWith(fullName)) {
      throw HTError.privateMember(varName);
    }
    decl.resolve();
    final setterFunc = decl as HTFunction;
    setterFunc.call(positionalArgs: [varValue]);
    return true;
  }

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

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