public class MBeanNotificationInfo extends MBeanFeatureInfo implements Cloneable
The MBeanNotificationInfo class is used to describe the
characteristics of the different notification instances
emitted by an MBean, for a given Java class of notification.
If an MBean emits notifications that can be instances of different Java classes,
then the metadata for that MBean should provide an MBeanNotificationInfo
object for each of these notification Java classes.
Instances of this class are immutable. Subclasses may be mutable but this is not recommended.
This class extends javax.management.MBeanFeatureInfo
and thus provides name and description fields.
The name field should be the fully qualified Java class name of
the notification objects described by this class.
The getNotifTypes method returns an array of
strings containing the notification types that the MBean may
emit. The notification type is a dot-notation string which
describes what the emitted notification is about, not the Java
class of the notification. A single generic notification class can
be used to send notifications of several types. All of these types
are returned in the string array result of the
getNotifTypes method.

equals in class MBeanFeatureInfoo - the object to compare to.o is an MBeanNotificationInfo
such that its MBeanFeatureInfo.getName(), MBeanFeatureInfo.getDescription(),
MBeanFeatureInfo.getDescriptor(),
and getNotifTypes() values are equal (not necessarily
identical) to those of this MBeanNotificationInfo. Two
notification type arrays are equal if their corresponding
elements are equal. They are not equal if they have the same
elements but in a different order.Object.hashCode()public int hashCode()
