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
.- Since:

Method Details
-
equals
Compares the specified
obj
parameter with thisOpenMBeanInfoSupport
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 forobj
parameters which are different implementations of theOpenMBeanInfo
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:
-
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 inequals
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 tonew java.util.HashSet(java.util.Arrays.asList(this.getSignature)).hashCode()
).This ensures that
t1.equals(t2)
implies thatt1.hashCode()==t2.hashCode()
for any twoOpenMBeanInfoSupport
instancest1
andt2
, as required by the general contract of the methodObject.hashCode()
.However, note that another instance of a class implementing the
OpenMBeanInfo
interface may be equal to thisOpenMBeanInfoSupport
instance as defined byequals(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 tohashCode
, 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:
-
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 totoString
, 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
