对于新版本的Nan
,以下内容的等效代码是什么:以下代码适用于 0.12.*,但不适用于 4.3.0 及更高版本。
//1)
//This is my object_
Persistent<Object> object_;
Local<Object> obj = Nan::New<Object>();
NanAssignPersistent(object_, obj); //Don't know what to replace with here
//2)
NanDisposePersistent(object_); //Don't know what to replace with here
nan
文档在此处展示了如何处理持久性。查看持久nan
测试也可能很有用。
例:
Local<Object> obj;
Local<Object> obj2;
// Create a persistent
Nan::Persistent<v8::Object> persistent(obj);
// Get a local handle to the persisted object
v8::Local<v8::Object> orig_obj = Nan::New(persistent);
// Change the persistent reference
persistent.Reset(obj2);
// Dispose of the persistent
persistent.Reset();
