This class holds information about memory usage in a given memory pool and is generated when that usage crosses a threshold specified by a MemoryPoolMXBean. Use the from( ) method to construct a MemoryNotificationInfo object from the user data of a javax.management.Notification object. Notifications and the javax.management package are beyond the scope of this book.
