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: 1.4 $
Author:: Adrian Brock.

Method Summary

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

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

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

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

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

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

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

int hashCode()
          Generates a hashcode for the implementation.

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

Method Detail

getClassName

public String getClassName()

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

Returns:: the fully qualified class name.

getDescription

public String getDescription()

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

Returns:: the description.

getAttributes

public MBeanAttributeInfo[] getAttributes()

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

Each instance should also implement OpenMBeanAttributeInfo

Returns:: the array of attributes.

getOperations

public MBeanOperationInfo[] getOperations()

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

Each instance should also implement OpenMBeanOperationInfo

Returns:: the array of operations.

getConstructors

public MBeanConstructorInfo[] getConstructors()

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

Each instance should also implement OpenMBeanConstructorInfo

Returns:: the array of constructors.

getNotifications

public MBeanNotificationInfo[] getNotifications()

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

Returns:: the array of notifications.

equals

public boolean equals(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

Parameters:: obj - the object to test
Returns:: true when above is true, false otherwise

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()

Returns:: the calculated hashcode

toString

public 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

Returns:: the string
