How to delete an AsyncWorker pointer? #430
Description
Hello!
How are you? I have a weird problem:
Napi::Value ArrayFireTestAsync(const Napi::CallbackInfo& info) {
Napi::Function callback = info[0].As<Napi::Function>();
// who is going to free up / delete this pointer???
ArrayTestWorker* testWorker = new ArrayTestWorker(callback);
testWorker->Queue();
return info.Env().Undefined();
}It looks like the testWorker is a pointer, but when is it going to be freed up/deleted? The example was no info how to delete this pointer... Is this valid code?

I was just playing with this exact thing last night. If you add the destructor method override in your asyncworker subclass and have it do something like
std::cout << "async worker destruction" << std:endl;then you should see it print to the console when it completes its Execute and OnOK methods and is destroyed. I think it is destroyed by default unless you explicitly tell it not to be.p3x-robot commentedon Jan 23, 2019
wow, thanks, i would have not thought it would be automatic for a pointer. so weird! that's all about my C++ .... 👍

i will wait for a little time if someone can explain what is happening... :)

The object instance does indeed self-destruct. We're adding a
SuppressDestruct()method for cases where self-destruction is undesirable.p3x-robot commentedon Jan 24, 2019
i was working for this kind of response. thank you very much!
