public class OpenMBeanInfoSupport extends MBeanInfo implements OpenMBeanInfo
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

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 the OpenMBeanInfo
interface,equals
method works properly for

the OpenMBeanInfo
interface.equals

instance;true

instance.Object.hashCode()
,
HashMap
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.

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.
