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.

public String toString()
ObjecttoString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
public boolean equals(Object o)
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(),
HashMappublic int hashCode()
ObjectHashMap.
The general contract of hashCode is:
hashCode method
must consistently return the same integer, provided no information
used in equals comparisons on the object is modified.
This integer need not remain consistent from one execution of an
application to another execution of the same application.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
class Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
JavaTM programming language.)
