pub struct PropertyCallbackArguments<'s> { /* private fields */ }

Implementations§

Returns the receiver. In many cases, this is the object on which the property access was intercepted. When using Reflect.get, Function.prototype.call, or similar functions, it is the object passed in as receiver or thisArg.

  void GetterCallback(Local<Name> name,
                      const v8::PropertyCallbackInfo<v8::Value>& info) {
     auto context = info.GetIsolate()->GetCurrentContext();

     v8::Local<v8::Value> a_this =
         info.This()
             ->GetRealNamedProperty(context, v8_str("a"))
             .ToLocalChecked();
     v8::Local<v8::Value> a_holder =
         info.Holder()
             ->GetRealNamedProperty(context, v8_str("a"))
             .ToLocalChecked();

    CHECK(v8_str("r")->Equals(context, a_this).FromJust());
    CHECK(v8_str("obj")->Equals(context, a_holder).FromJust());

    info.GetReturnValue().Set(name);
  }

  v8::Local<v8::FunctionTemplate> templ =
  v8::FunctionTemplate::New(isolate);
  templ->InstanceTemplate()->SetHandler(
      v8::NamedPropertyHandlerConfiguration(GetterCallback));
  LocalContext env;
  env->Global()
      ->Set(env.local(), v8_str("obj"), templ->GetFunction(env.local())
                                           .ToLocalChecked()
