Method Detail

• loadMBeans

  java.util.List<javax.management.ObjectName> loadMBeans(java.lang.Object source,
                                                       java.lang.ClassLoader cl)
                                                         throws java.lang.Exception

  Load an extended mlet file. The source can be an URL, File or InputStream. All mbeans will be instantiated, registered and the attributes will be set. The result is a list of ObjectNames.

  Parameters:

  source - InputStream or URL of the file

  cl - ClassLoader to be used to load the mbeans, or null to use the default JMX mechanism ( i.e. all registered loaders )

  Returns:

  List of ObjectName for the loaded mbeans

  Throws:

  java.lang.Exception

  Since:

  1.1

• invoke

  void invoke(java.util.List<javax.management.ObjectName> mbeans,
            java.lang.String operation,
            boolean failFirst)
              throws java.lang.Exception

  Invoke an operation on a set of mbeans.

  Parameters:

  mbeans - List of ObjectNames

  operation - Operation to perform. Typically "init" "start" "stop" or "destroy"

  failFirst - Behavior in case of exceptions - if false we'll ignore errors

  Throws:

  java.lang.Exception

• registerComponent

  void registerComponent(java.lang.Object bean,
                       java.lang.String oname,
                       java.lang.String type)
                         throws java.lang.Exception

  Register a bean by creating a modeler mbean and adding it to the MBeanServer. If metadata is not loaded, we'll look up and read a file named "mbeans-descriptors.ser" or "mbeans-descriptors.xml" in the same package or parent. If the bean is an instance of DynamicMBean. it's metadata will be converted to a model mbean and we'll wrap it - so modeler services will be supported If the metadata is still not found, introspection will be used to extract it automatically. If an mbean is already registered under this name, it'll be first unregistered. If the component implements MBeanRegistration, the methods will be called. If the method has a method "setRegistry" that takes a RegistryMBean as parameter, it'll be called with the current registry.

  Parameters:

  bean - Object to be registered

  oname - Name used for registration

  type - The type of the mbean, as declared in mbeans-descriptors. If null, the name of the class will be used. This can be used as a hint or by subclasses.

  Throws:

  java.lang.Exception

  Since:

  1.1

• unregisterComponent

  void unregisterComponent(java.lang.String oname)

  Unregister a component. We'll first check if it is registered, and mask all errors. This is mostly a helper.

  Parameters:

  oname -

  Since:

  1.1

• getId

  int getId(java.lang.String domain,
          java.lang.String name)

  Return an int ID for faster access. Will be used for notifications and for other operations we want to optimize.

  Parameters:

  domain - Namespace

  name - Type of the notification

  Returns:

  An unique id for the domain:name combination

  Since:

  1.1

• stop

  void stop()

  Reset all metadata cached by this registry. Should be called to support reloading. Existing mbeans will not be affected or modified. It will be called automatically if the Registry is unregistered.

  Since:

  1.1

• loadMetadata

  void loadMetadata(java.lang.Object source)
                    throws java.lang.Exception

  Load descriptors. The source can be a File, URL pointing to an mbeans-descriptors.xml. Also ( experimental for now ) a ClassLoader - in which case META-INF/ will be used.

  Parameters:

  source -

  Throws:

  java.lang.Exception
