Customization hook: cache the MBeanInfo built for this object.

  Customization hook: cache the MBeanInfo built for this object.

Subclasses may redefine this method in order to implement their own caching policy. The default implementation stores info in this instance. A subclass can define other policies, such as not saving info (so it is reconstructed every time StandardMBean.getMBeanInfo() is called) or sharing a unique MBeanInfo object when several StandardMBean instances have equal MBeanInfo values.
Parameters:
- info - the new MBeanInfo to cache. Any previously cached value is discarded. This parameter may be null, in which case there is no new cached value.

  Customization hook: Return the MBeanInfo cached for this object.

  Customization hook: Return the MBeanInfo cached for this object.

Subclasses may redefine this method in order to implement their own caching policy. The default implementation stores one MBeanInfo object per instance.
Returns: The cached MBeanInfo, or null if no MBeanInfo is cached.

this MBean.


Subclasses may redefine this method in order to supply their
custom class name. The default implementation returns
info.getClassName().
Returns: the class name for the new MBeanInfo.
Parameters:
- info - The default MBeanInfo derived by reflection.

  Customization hook: Get the MBeanConstructorInfo[] that will be used in the MBeanInfo returned by this MBean.

  Customization hook:
Get the MBeanConstructorInfo[] that will be used in the MBeanInfo
returned by this MBean.


By default, this method returns null if the wrapped
implementation is not this. Indeed, if the wrapped
implementation is not this object itself, it will not be possible
to recreate a wrapped implementation by calling the implementation
constructors through MBeanServer.createMBean(...).

Otherwise, if the wrapped implementation is this,
ctors is returned.


Subclasses may redefine this method in order to modify this
behavior, if needed.
Returns: the MBeanConstructorInfo[] for the new MBeanInfo.
Parameters:
- ctors - The default MBeanConstructorInfo[] derived by reflection.
- impl - The wrapped implementation. If null is passed, the wrapped implementation is ignored and ctors is returned.

This method implements DynamicMBean.getMBeanInfo().

This method first calls StandardMBean.getCachedMBeanInfo() in order to retrieve the cached MBeanInfo for this MBean, if any. If the MBeanInfo returned by StandardMBean.getCachedMBeanInfo() is not null, then it is returned.
Otherwise, this method builds a default MBeanInfo for this MBean, using the Management Interface specified for this MBean.

While building the MBeanInfo, this method calls the customization hooks that make it possible for subclasses to supply their custom descriptions, parameter names, etc...
Finally, it calls cacheMBeanInfo() in order to cache the new MBeanInfo.
Returns: The cached MBeanInfo for that MBean, if not null, or a newly built MBeanInfo if none was cached.

methods.

  Allows the MBean to perform any operations needed after having been unregistered in the MBean server.

 

Allows the MBean to perform any operations needed after having been unregistered in the MBean server.

The default implementation of this method does nothing for Standard MBeans. For MXBeans, it removes any information that was recorded by the preRegister method.

It is good practice for a subclass that overrides this method to call the overridden method via super.postRegister(...). This is necessary if this object is an MXBean that is referenced by attributes or operations in other MXBeans.

Since: 1.6

  Allows the MBean to perform any operations needed after having been registered in the MBean server or after the registration has failed.

 

Allows the MBean to perform any operations needed after having been registered in the MBean server or after the registration has failed.

The default implementation of this method does nothing for Standard MBeans. For MXBeans, it undoes any work done by preRegister if registration fails.

It is good practice for a subclass that overrides this method to call the overridden method via super.postRegister(...). This is necessary if this object is an MXBean that is referenced by attributes or operations in other MXBeans.

Parameters:
- registrationDone - Indicates whether or not the MBean has been successfully registered in the MBean server. The value false means that the registration phase has failed.
Since: 1.6

  Allows the MBean to perform any operations it needs before being unregistered by the MBean server.

 

Allows the MBean to perform any operations it needs before being unregistered by the MBean server.

The default implementation of this method does nothing.

It is good practice for a subclass that overrides this method to call the overridden method via super.preDeegister(...).

Throws:
- Exception - no checked exceptions are throw by this method but {@code Exception} is declared so that subclasses can override this method and throw their own exceptions.
Since: 1.6

  Allows the MBean to perform any operations it needs before being registered in the MBean server.

 

Allows the MBean to perform any operations it needs before being registered in the MBean server. If the name of the MBean is not specified, the MBean can provide a name for its registration. If any exception is raised, the MBean will not be registered in the MBean server.

The default implementation of this method returns the name parameter. It does nothing else for Standard MBeans. For MXBeans, it records the MBeanServer and ObjectName parameters so they can be used to translate inter-MXBean references.

It is good practice for a subclass that overrides this method to call the overridden method via super.preRegister(...). This is necessary if this object is an MXBean that is referenced by attributes or operations in other MXBeans.

Returns: The name under which the MBean is to be registered. This value must not be null. If the name parameter is not null, it will usually but not necessarily be the returned value.
Parameters:
- server - The MBean server in which the MBean will be registered.
- name - The object name of the MBean. This name is null if the name parameter to one of the createMBean or registerMBean methods in the {@link MBeanServer} interface is null. In that case, this method must return a non-null ObjectName for the new MBean.
Throws:
- IllegalArgumentException - if this is an MXBean and {@code name} is null.
- InstanceAlreadyExistsException - if this is an MXBean and it has already been registered under another name (in this MBean Server or another).
- Exception - no other checked exceptions are thrown by this method but {@code Exception} is declared so that subclasses can override the method and throw their own exceptions.
Since: 1.6

  Replace the implementation object wrapped in this object.

 

Replace the implementation object wrapped in this object.

Parameters:
- implementation - The new implementation of this Standard MBean (or MXBean). The implementation object must implement the Standard MBean (or MXBean) interface that was supplied when this StandardMBean was constructed.
Throws:
- IllegalArgumentException - if the given implementation is null.
- NotCompliantMBeanException - if the given implementation does not implement the Standard MBean (or MXBean) interface that was supplied at construction.
