public class OpenMBeanInfoSupport extends MBeanInfo implements OpenMBeanInfo
The OpenMBeanInfoSupport
class describes the management information of an open MBean: it is a subclass of MBeanInfo
, and it implements the OpenMBeanInfo
interface. Note that an open MBean is recognized as such if its getMBeanInfo()
method returns an instance of a class which implements the OpenMBeanInfo interface, typically OpenMBeanInfoSupport
.

Method Detail
equals
public boolean equals(Object obj)
Compares the specified obj
parameter with this OpenMBeanInfoSupport
instance for equality.
Returns true
if and only if all of the following statements are true:
-
obj
is non null, -
obj
also implements theOpenMBeanInfo
interface, - their class names are equal
- their infos on attributes, constructors, operations and notifications are equal
equals
method works properly for obj
parameters which are different implementations of the OpenMBeanInfo
interface.- Specified by:
-
equals
in interfaceOpenMBeanInfo
- Overrides:
-
equals
in classMBeanInfo
- Parameters:
-
obj
- the object to be compared for equality with thisOpenMBeanInfoSupport
instance; - Returns:
-
true
if the specified object is equal to thisOpenMBeanInfoSupport
instance. - See Also:
-
Object.hashCode()
,HashMap
hashCode
public int hashCode()
Returns the hash code value for this
OpenMBeanInfoSupport
instance.
The hash code of an OpenMBeanInfoSupport
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
OpenMBeanInfoSupport
instances t1
and t2
, as required by the general contract of the method Object.hashCode()
.
However, note that another instance of a class implementing the OpenMBeanInfo
interface may be equal to this
OpenMBeanInfoSupport
instance as defined by equals(java.lang.Object)
, but may have a different hash code if it is calculated differently.
As OpenMBeanInfoSupport
instances are immutable, the hash code for this instance is calculated once, on the first call to hashCode
, and then the same value is returned for subsequent calls.
- Specified by:
-
hashCode
in interfaceOpenMBeanInfo
- Overrides:
-
hashCode
in classObject
- Returns:
- the hash code value for this
OpenMBeanInfoSupport
instance - See Also:
-
Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
toString
public String toString()
Returns a string representation of this
OpenMBeanInfoSupport
instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanInfoSupport
), the MBean class name, the string representation of infos on attributes, constructors, operations and notifications of the described MBean and the string representation of the descriptor.
As OpenMBeanInfoSupport
instances are immutable, the string representation for this instance is calculated once, on the first call to toString
, and then the same value is returned for subsequent calls.
- Specified by:
-
toString
in interfaceOpenMBeanInfo
- Overrides:
-
toString
in classObject
- Returns:
- a string representation of this
OpenMBeanInfoSupport
instance
