Package: Notifications
Header: Poco/Observer.h
Description
This template class implements an adapter that sits between a NotificationCenter and an object receiving notifications from it. It is quite similar in concept to the RunnableAdapter, but provides some NotificationCenter specific additional methods. See the NotificationCenter class for information on how to use this template class.
Instead of the Observer class template, you might want to use the NObserver class template, which uses an AutoPtr to pass the Notification to the callback function, thus freeing you from memory management issues.
