POCO event mechanism

[luisao]

Dear all,

I am new using POCO. I couldn´t find many good examples about the notification center using POCO.

Do anybody has experience with it?

Currently I am trying to notify several threads the same notification. But I found the problem: who is the responsable for deleting the notification object?

thanks guys,

Let's see what does documentation say:

The handler method gets co-ownership of the Notification object and must release it when done. This is best done with an AutoPtr:

Code: Select all

void MyClass::handleNotification(MyNotification* pNf)
{
   AutoPtr<MyNotification> nf(pNf);
   ///         ...
}

Alternatively, the NObserver class template can be used to register a callback method. In this case, the callback method receives the Notification in an AutoPtr and thus does not have to deal with object ownership issues:

Code: Select all

void MyClass::handleNotification(const AutoPtr<MyNotification>& pNf)
{
           ...
}
