Class MBeanNotificationInfo

java.lang.Object

javax.management.MBeanFeatureInfo

javax.management.MBeanNotificationInfo

All Implemented Interfaces:

Serializable, Cloneable, DescriptorRead

Direct Known Subclasses:

ModelMBeanNotificationInfo

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.

Constructor Details

MBeanNotificationInfo

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

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.

MBeanNotificationInfo

public MBeanNotificationInfo(String[] notifTypes,
 String name,
 String description,
 Descriptor descriptor)

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.

descriptor - The descriptor for the notifications. This may be null which is equivalent to an empty descriptor.

1.6

Method Details

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.

Overrides:

clone in class Object

Returns:

a clone of this instance.

• Cloneable

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 MBeanNotificationInfo to another.

Overrides:

equals in class MBeanFeatureInfo

Parameters:

o - the object to compare to.

Returns:

true if and only if 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.
