javax.management.openmbean
Interface OpenMBeanInfo

All Known Implementing Classes:: OpenMBeanInfoSupport

public interface OpenMBeanInfo

An MBean is an OpenMBean when its getMBeanInfo() returns an MBeanInfo implementing this interface and extending javax.management.MBeanInfo.

OpenMBeanInfoSupport is an example of such a class.

The MBean info classes should be the OpenInfo versions. e.g. an OpenMBeanAttributeInfo instead of MBeanAttributeInfo.

Version:: $Revision: 1.1.2.1 $

Method Summary

boolean equals(java.lang.Object obj)
          Compares an object for equality with the implementing class.

javax.management.MBeanAttributeInfo[] getAttributes()
          Retrieve an array of OpenMBeanAttributeInfos describing each attribute of the open mbean.

java.lang.String getClassName()
          Retrieve the fully qualified class name of the open MBean the implementation of this interface describes.

javax.management.MBeanConstructorInfo[] getConstructors()
          Retrieve an array of OpenMBeanConstructorInfos describing each constructor of the open mbean.

java.lang.String getDescription()
          Retrieve a human readable description of the open MBean the implementation of this interface describes.

javax.management.MBeanNotificationInfo[] getNotifications()
          Retrieve an array of MBeanNotificationInfos describing each notification of the open mbean.

javax.management.MBeanOperationInfo[] getOperations()
          Retrieve an array of OpenMBeanOperationInfos describing each operation of the open mbean.

int hashCode()
          Generates a hashcode for the implementation.

java.lang.String toString()
          A string representation of the open mbean info.

Method Detail

getClassName

public java.lang.String getClassName()

Retrieve the fully qualified class name of the open MBean the implementation of this interface describes.

getDescription

public java.lang.String getDescription()

Retrieve a human readable description of the open MBean the implementation of this interface describes.

getAttributes

public javax.management.MBeanAttributeInfo[] getAttributes()

Retrieve an array of OpenMBeanAttributeInfos describing each attribute of the open mbean.

Each instance should also implement OpenMBeanAttributeInfo

getConstructors

public javax.management.MBeanConstructorInfo[] getConstructors()

Retrieve an array of OpenMBeanConstructorInfos describing each constructor of the open mbean.

Each instance should also implement OpenMBeanConstructorInfo

getOperations

public javax.management.MBeanOperationInfo[] getOperations()

Retrieve an array of OpenMBeanOperationInfos describing each operation of the open mbean.

Each instance should also implement OpenMBeanOperationInfo

getNotifications

public javax.management.MBeanNotificationInfo[] getNotifications()

Retrieve an array of MBeanNotificationInfos describing each notification of the open mbean.

equals

public boolean equals(java.lang.Object obj)

Compares an object for equality with the implementing class.

The object is not null
The object implements the open mbean info interface
The getClassName() methods return strings that are equal
The information objects (attributes, constructors, operations and notifications) are the equal

hashCode

public int hashCode()

Generates a hashcode for the implementation.

The hashcode is the sum of the hashcodes for
getClassName()
java.util.HashSet(java.util.Arrays.asList(getAttributes()).hashCode()
java.util.HashSet(java.util.Arrays.asList(getConstructors()).hashCode()
java.util.HashSet(java.util.Arrays.asList(getOperations()).hashCode()
java.util.HashSet(java.util.Arrays.asList(getNotifications()).hashCode()

toString

public java.lang.String toString()

A string representation of the open mbean info.

It is made up of
The implementing class
getClassName()
toString() for each of the info arrays
