javax.management
public class MBeanNotificationInfo extends MBeanFeatureInfo implements Cloneable
Describes the notifications emitted by a management bean. An instance of this class is specific to notifications involving a particular type of object. A new instance should be created for each Java class used for notifications, and the Java class name forms the name of the instance. Each instance lists a number of notification types; these are not types in the sense of different Java classes, but instead form the names of notifications following the same syntax as Java property and package names.
For instance, a management bean may emit two notifications
containing String
objects. Both would be described
using one instance of this class, with a member of the array
returned by getNotifTypes()
for each one. If another
notification containing a Date
object were to
be added, this would require a new instance of this class.
The information in this class is immutable as standard. Of course, subclasses may change this, but this behaviour is not recommended.

returns true for
a comparison of both the name and description of this
notification with that of the specified object, and the two
notification type arrays contain the same elements in the same
order (but one may be longer than the other).equals

public String toString()
Returns a textual representation of this instance. This
is constructed using the class name

the name and description of the notification and the
contents of the array of types.
As instances of this class are immutable, the return value is computed just once for each instance and reused throughout its life.
