memberSet method

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

HTInstance overrided HTEntity's memberSet, with a new named parameter cast. If cast is provided, then the instance will only search that cast's corresponed HTInstanceNamespace.

Implementation

@override
void memberSet(String varName, dynamic varValue,
    {String? from, String? cast, bool throws = true}) {
  final setter = '${InternalIdentifier.setter}$varName';

  if (cast == null) {
    for (final space in _namespaces.values) {
      if (space.symbols.containsKey(varName)) {
        final decl = space.symbols[varName]!;
        if (decl.isPrivate &&
            from != null &&
            !from.startsWith(namespace.fullName)) {
          throw HTError.privateMember(varName);
        }
        decl.resolve();
        decl.value = varValue;
        return;
      } else if (space.symbols.containsKey(setter)) {
        final decl = space.symbols[setter]!;
        if (decl.isPrivate &&
            from != null &&
            !from.startsWith(namespace.fullName)) {
          throw HTError.privateMember(varName);
        }
        decl.resolve();
        final method = decl as HTFunction;
        method.namespace = namespace;
        method.instance = this;
        method.call(positionalArgs: [varValue]);
        return;
      }
    }
  } else {
