Methods Summary
public 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. param domain Namespace param name Type of the notification return An unique id for the domain:name combination since 1.1
public void	invoke(java.util.List mbeans, java.lang.String operation, boolean failFirst) Invoke an operation on a set of mbeans. param mbeans List of ObjectNames param operation Operation to perform. Typically "init" "start" "stop" or "destroy" param failFirst Behavior in case of exceptions - if false we'll ignore errors throws Exception
public java.util.List	loadMBeans(java.lang.Object source, java.lang.ClassLoader cl) 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. param source InputStream or URL of the file param cl ClassLoader to be used to load the mbeans, or null to use the default JMX mechanism ( i.e. all registered loaders ) return List of ObjectName for the loaded mbeans throws Exception since 1.1
public void	loadMetadata(java.lang.Object source) 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. param source
public void	registerComponent(java.lang.Object bean, java.lang.String oname, java.lang.String type) 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. param bean Object to be registered param oname Name used for registration param 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. since 1.1
public 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
public 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. param oname since 1.1
