public interface OpenMBeanInfo
Describes an Open MBean: an Open MBean is recognized as such if
its getMBeanInfo()
method returns an instance of a class which
implements the OpenMBeanInfo
interface, typically OpenMBeanInfoSupport
.
This interface declares the same methods as the class MBeanInfo
. A class implementing this interface
(typically OpenMBeanInfoSupport
) should extend MBeanInfo
.
The getAttributes()
, getOperations()
and
getConstructors()
methods of the implementing class should
return at runtime an array of instances of a subclass of MBeanAttributeInfo
, MBeanOperationInfo
or MBeanConstructorInfo
respectively which implement the OpenMBeanAttributeInfo
, OpenMBeanOperationInfo
or OpenMBeanConstructorInfo
interface respectively.
Modifier and Type | Method and Description |
---|---|
boolean |
equals(Object obj)
Compares the specified obj parameter with this
OpenMBeanInfo instance for equality. |
MBeanAttributeInfo[] |
getAttributes()
Returns an array of OpenMBeanAttributeInfo instances
describing each attribute in the open MBean described by this
OpenMBeanInfo instance.
|
String |
getClassName()
Returns the fully qualified Java class name of the open MBean
instances this OpenMBeanInfo describes.
|
MBeanConstructorInfo[] |
getConstructors()
Returns an array of OpenMBeanConstructorInfo instances
describing each constructor in the open MBean described by this
OpenMBeanInfo instance.
|
String |
getDescription()
Returns a human readable description of the type of open MBean
instances this OpenMBeanInfo describes.
|
MBeanNotificationInfo[] |
getNotifications()
Returns an array of MBeanNotificationInfo instances
describing each notification emitted by the open MBean
described by this OpenMBeanInfo instance.
|
MBeanOperationInfo[] |
getOperations()
Returns an array of OpenMBeanOperationInfo instances
describing each operation in the open MBean described by this
OpenMBeanInfo instance.
|
int |
hashCode()
Returns the hash code value for this
OpenMBeanInfo instance. |
String |
toString()
Returns a string representation of this
OpenMBeanInfo instance. |

boolean equals(Object obj)
OpenMBeanInfo
instance for equality.
Returns true if and only if all of the following statements are true:
OpenMBeanInfo
interface,OpenMBeanInfo
interface.
equals
in class Object
obj
- the object to be compared for equality with this OpenMBeanInfo
instance;true
if the specified object is equal to this OpenMBeanInfo
instance.Object.hashCode()
,
HashMap
int hashCode()
OpenMBeanInfo
instance.
The hash code of an OpenMBeanInfo
instance is the sum of the hash codes
of all elements of information used in equals
comparisons
(ie: its class name, and its infos on attributes, constructors, operations and notifications,
where the hashCode of each of these arrays is calculated by a call to
new java.util.HashSet(java.util.Arrays.asList(this.getSignature)).hashCode()).
This ensures that t1.equals(t2)
implies that t1.hashCode()==t2.hashCode()
for any two OpenMBeanInfo
instances t1
and t2
,
as required by the general contract of the method
Object.hashCode()
.

String toString()
OpenMBeanInfo
instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanInfo
),
the MBean class name,
and the string representation of infos on attributes, constructors, operations and notifications of the described MBean.
