javax.management
Class MBeanNotificationInfo
- Cloneable, Serializable
Describes the notifications emitted by a management bean.
An instance of this class is specific to notifications
involving a particular type of object. A new instance
should be created for each Java class used for notifications,
and the Java class name forms the name of the instance.
Each instance lists a number of notification types; these
are not types in the sense of different Java classes, but
instead form the names of notifications following the same
syntax as Java property and package names.
For instance, a management bean may emit two notifications
containing
String objects. Both would be described
using one instance of this class, with a member of the array
returned by
getNotifTypes() for each one. If another
notification containing a
Date object were to
be added, this would require a new instance of this class.
The information in this class is immutable as standard.
Of course, subclasses may change this, but this
behaviour is not recommended.
Object | clone()- Returns a clone of this instance.
|
boolean | equals(Object obj)- Compares this feature with the supplied object.
|
String[] | getNotifTypes()- Returns the notification types that the management bean may emit.
|
int | hashCode()- Returns the hashcode of the notification information as the sum
of the hashcode of the superclass and the hashcode of the types
array.

String | toString()-
Returns a textual representation of this instance.

MBeanNotificationInfo
public MBeanNotificationInfo(String[] types,
String name,
String description) Constructs a new
MBeanNotificationInfo with the
specified name, description and notification types. The
notification types array may be
null or of
zero length, in order to indicate the absence of any types.
types - an array of String objects,
containing the names of the notifications emitted
of this Java type. The names use the dot notation
familiar from Java property and package names.name - the name of the Java class the notifications described
by this object are instances of.description - a description of the data.
clone
public Object clone()
Returns a clone of this instance. The clone is created
using just the method provided by
Object.
Thus, the clone is just a shallow clone as returned by
that method, and does not contain any deeper cloning based
on the subject of this class.
- clone in interface Object
- a clone of this instance.
equals
public boolean equals(Object obj)
Compares this feature with the supplied object. This returns
true iff the object is an instance of
MBeanNotificationInfo,
Object.equals() returns true for
a comparison of both the name and description of this
notification with that of the specified object, and the two
notification type arrays contain the same elements in the same
order (but one may be longer than the other).
- equals in interface MBeanFeatureInfo
obj - the object to compare.
- true if the object is a
MBeanNotificationInfo
instance,
name.equals(object.getName()),
description.equals(object.getDescription())
and the corresponding elements of the type arrays are
equal.
getNotifTypes
public String[] getNotifTypes()
Returns the notification types that the management bean may emit.
The notification types are strings using the dot notation
familiar from Java property and package names. Changing the
returned array does not affect the values retained by this
instance.
hashCode
public int hashCode()
Returns the hashcode of the notification information as the sum
of the hashcode of the superclass and the hashcode of the types
array.
- hashCode in interface MBeanFeatureInfo
- the hashcode of the notification information.
toString
public String toString()
Returns a textual representation of this instance. This
is constructed using the class name
(
javax.management.MBeanNotificationInfo),
the name and description of the notification and the
contents of the array of types.
As instances of this class are immutable, the return value
is computed just once for each instance and reused
throughout its life.
- toString in interface MBeanFeatureInfo
- a @link{java.lang.String} instance representing
the instance in textual form.
