Class MBeanNotificationInfo

java.lang.Object
  javax.management.MBeanFeatureInfo
      javax.management.MBeanNotificationInfo

All Implemented Interfaces:

Cloneable, Serializable

Direct Known Subclasses:

ModelMBeanNotificationInfo

---

public class MBeanNotificationInfo

extends MBeanFeatureInfo

implements Cloneable, Serializable

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 notifcations 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.

Constructor Detail

MBeanNotificationInfo

public MBeanNotificationInfo(String[] notifTypes,
                             String name,
                             String description)
                      throws IllegalArgumentException

Constructs an MBeanNotificationInfo object.

Parameters:

notifTypes - The array of strings (in dot notation) containing the notification types that the MBean may emit. This may be null with the same effect as a zero-length array.

name - The fully qualified Java class name of the described notifications.

description - A human readable description of the data.

Throws:

IllegalArgumentException - if name is not a valid Java class name. Java reserved words are not considered illegal here.

Method Detail

clone

public Object clone()

Returns a shallow clone of this instance. The clone is obtained by simply calling super.clone(), thus calling the default native shallow cloning mechanism implemented by Object.clone(). No deeper cloning of any internal field is made.

---

getNotifTypes

public String[] getNotifTypes()

Returns the array of strings (in dot notation) containing the notification types that the MBean may emit.

Returns:

the array of strings. Changing the returned array has no effect on this MBeanNotificationInfo.

---

equals

public boolean equals(Object o)

Compare this MBeanAttributeInfo to another.

Overrides:

equals in class MBeanFeatureInfo

Parameters:

o - the object to compare to.

Returns:

true iff o is an MBeanNotificationInfo such that its MBeanFeatureInfo.getName(), MBeanFeatureInfo.getDescription(), 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.

---

hashCode

public int hashCode()

Overrides:

hashCode in class MBeanFeatureInfo
