构造一个Local对象返回。即Local内部管理用户定义的对象(String::New函数执行完后,他里面定义的result,即handle被析构)。如下图。 在这里插入图片描述当HandleScope析构的时候,他会释放用户定义的对象的内存,然后Local对象本身是在栈上分配的,也会被析构。这就是v8用本地handle(临时handle)管理堆对象的大致原理。
Handle result = i::Factory::NewStringFromUtf8(i::Vector<const char>(data, length)); return Utils::ToLocal(result); } Local<v8::String> Utils::ToLocal(v8::internal::Handle<v8::internal::String> obj) { return Local<String>(reinterpret_cast<String*>(obj.location())); } 我们在看下...
