With recent versions of v8 the SetWeak method has changed and the
Persistent<Value>* parameter has been dropped from the destructor callback.
The destructor callback function is **supposed** to Reset() the persistent
or its a leak.
If you don't V8 crashes and tells you this:
Check failed: Handle not reset in first callback. See comments on
|v8::WeakCallbackInfo
Old signature:
void MyClass::DestructorCallback(Isolate* pIsolate, Persistent<Value>*
value, MyClass* pObj)
New signature
void MyClass::DestructorCallback(const WeakCallbackInfo<MyClass>& oValue)
If I call it like this:
Persistent<Object> obj(isolate, objLocal);
obj.SetWeak<MyClass>(pMyObject, MyClass::DestructorCallback,
WeakCallbackType::kParameter);
How can I pass the Persistent into my DestructorCallback function so I can
Reset it??
Persistent cannot be copied.
So how can I Reset() it in the callback?
Any help would be great.
Also the WeakCallbackType::kParameter vs WeakCallbackType::kFinalizer
thing has me confuzeled too.
Which is the right type to use?
Thanks!
