OpenMBeanInfoSupport
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 | Description |
---|---|---|
boolean |
equals |
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. |

OpenMBeanInfo
describes.MBeanAttributeInfo[] getAttributes()
OpenMBeanAttributeInfo
instances describing each attribute in the open MBean described by this OpenMBeanInfo
instance. Each instance in the returned array should actually be a subclass of MBeanAttributeInfo
which implements the OpenMBeanAttributeInfo
interface (typically OpenMBeanAttributeInfoSupport
).MBeanOperationInfo[] getOperations()
OpenMBeanOperationInfo
instances describing each operation in the open MBean described by this OpenMBeanInfo
instance. Each instance in the returned array should actually be a subclass of MBeanOperationInfo
which implements the OpenMBeanOperationInfo
interface (typically OpenMBeanOperationInfoSupport
).MBeanConstructorInfo[] getConstructors()
OpenMBeanConstructorInfo
instances describing each constructor in the open MBean described by this OpenMBeanInfo
instance. Each instance in the returned array should actually be a subclass of MBeanConstructorInfo
which implements the OpenMBeanConstructorInfo
interface (typically OpenMBeanConstructorInfoSupport
).MBeanNotificationInfo[] getNotifications()
MBeanNotificationInfo
instances describing each notification emitted by the open MBean described by 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,equals
method works properly for obj parameters which are different implementations of the OpenMBeanInfo
interface.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.
