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 anMBeanNotificationInfo
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 providesname
anddescription
fields. Thename
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 thegetNotifTypes
method.- Since:

MBeanNotificationInfo
public MBeanNotificationInfo(String[] notifTypes, String name, String description)
Constructs anMBeanNotificationInfo
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 anMBeanNotificationInfo
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.- Since:
- 1.6

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.
-
toString
public String toString()
Description copied from class:Object
Returns a string representation of the object. In general, thetoString
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 classObject
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())
-
equals
public boolean equals(Object o)
Compare this MBeanNotificationInfo to another.- Overrides:
equals
in classMBeanFeatureInfo
- Parameters:
o
- the object to compare to.- Returns:
- true if and only if
o
is an MBeanNotificationInfo such that itsMBeanFeatureInfo.getName()
,MBeanFeatureInfo.getDescription()
,MBeanFeatureInfo.getDescriptor()
, andgetNotifTypes()
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. - See Also:
Object.hashCode()
,HashMap

hashCode
public int hashCode()
Description copied from class:Object
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided byHashMap
.The general contract of
hashCode
is:- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
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. - If two objects are equal according to the
equals(Object)
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
Object.equals(java.lang.Object)
method, then calling thehashCode
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.)- Overrides:
hashCode
in classMBeanFeatureInfo
- Returns:
- a hash code value for this object.

,System.identityHashCode(java.lang.Object)

an execution of a Java application, the
