public class ModelMBeanNotificationInfo
extends MBeanNotificationInfo
implements DescriptorAccess

The ModelMBeanNotificationInfo object describes a notification emitted by a ModelMBean. It is a subclass of MBeanNotificationInfo with the addition of an associated Descriptor and an implementation of the Descriptor interface.

The fields in the descriptor are defined, but not limited to, the following. Note that when the Type in this table is Number, a String that is the decimal representation of a Long can also be used.

ModelMBeanNotificationInfo Fields

Name	Type	Meaning
name	String	Notification name.
descriptorType	String	Must be "notification".
severity	Number	0-6 where 0: unknown; 1: non-recoverable; 2: critical, failure; 3: major, severe; 4: minor, marginal, error; 5: warning; 6: normal, cleared, informative
messageID	String	Unique key for message text (to allow translation, analysis).
messageText	String	Text of notification.
log	String	T - log message, F - do not log message.
logfile	String	fully qualified file name appropriate for operating system.
visibility	Number	1-4 where 1: always visible 4: rarely visible.
presentationString	String	XML formatted string to allow presentation of data.

The default descriptor contains the name, descriptorType, displayName and severity(=6) fields. The default value of the name and displayName fields is the name of the Notification class (as specified by the name parameter of the ModelMBeanNotificationInfo constructor).

The serialVersionUID of this class is -7445681389570207141L.

Constructor Details

ModelMBeanNotificationInfo

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

Constructs a ModelMBeanNotificationInfo object with a default descriptor.

Parameters:

notifTypes - The array of strings (in dot notation) containing the notification types that may be emitted.

name - The name of the Notification class.

description - A human readable description of the Notification. Optional.

ModelMBeanNotificationInfo

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

Constructs a ModelMBeanNotificationInfo object.

Parameters:

notifTypes - The array of strings (in dot notation) containing the notification types that may be emitted.

name - The name of the Notification class.

description - A human readable description of the Notification. Optional.

descriptor - An instance of Descriptor containing the appropriate metadata for this instance of the MBeanNotificationInfo. If it is null a default descriptor will be created. If the descriptor does not contain the fields "displayName" or "severity", the missing ones are added with their default values.

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is not equal to parameter name, or descriptor field "descriptorType" is not equal to "notification".

ModelMBeanNotificationInfo

public ModelMBeanNotificationInfo(ModelMBeanNotificationInfo inInfo)

Constructs a new ModelMBeanNotificationInfo object from this ModelMBeanNotfication Object.

Parameters:

inInfo - the ModelMBeanNotificationInfo to be duplicated

Method Details

clone

public Object clone()

Creates and returns a new ModelMBeanNotificationInfo which is a duplicate of this ModelMBeanNotificationInfo.

Overrides:

clone in class MBeanNotificationInfo

Returns:

a clone of this instance.

See Also:

• Cloneable

getDescriptor

public Descriptor getDescriptor()

Returns a copy of the associated Descriptor for the ModelMBeanNotificationInfo.

Specified by:

getDescriptor in interface DescriptorRead

Overrides:

getDescriptor in class MBeanFeatureInfo

Returns:

Descriptor associated with the ModelMBeanNotificationInfo object.

See Also:

• setDescriptor(javax.management.Descriptor)

setDescriptor

public void setDescriptor(Descriptor inDescriptor)

Sets associated Descriptor (full replace) for the ModelMBeanNotificationInfo If the new Descriptor is null, then the associated Descriptor reverts to a default descriptor. The Descriptor is validated before it is assigned. If the new Descriptor is invalid, then a RuntimeOperationsException wrapping an IllegalArgumentException is thrown.

Specified by:

setDescriptor in interface DescriptorAccess

Parameters:

inDescriptor - replaces the Descriptor associated with the ModelMBeanNotification interface

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException for invalid Descriptor.

• getDescriptor()

toString

public String toString()

Returns a human readable string containing ModelMBeanNotificationInfo.

Overrides:

toString in class Object

Returns:

a string describing this object.
