[jboss-dev-forums] [Design the new POJO MicroContainer] - InstanceClassFactory extension to the ManagedObjectFactory

[scott.stark@jboss.org]

In order to deal with wrapping metadata instances like the ServiceMetaData class, I need to add an InstanceClassFactory plugin to the ManagedObjectFactory. This allows for the management annotations to be on the underlying mbean instance:


  | public interface InstanceClassFactory
  | {
  |    /**
  |     * Return the Class that represents the root ManagedObject to scan
  |     * for management object related annotations.
  |     * 
  |     * @param instance - the instance a ManagedObject is to be created for.
  |     * @return the Class that represents the root ManagedObject.
  |     */
  |    public Class<? extends Serializable> getManagedObjectClass(Serializable instance);
  | }
  | 

This allows one to mark up the instance the mbean service wraps. The alternative would be to assume the ServiceMetaData jmx representation is the ManagedObject. I don't think that is generally the case as the interfaces were more a description of the bean service rather than the management interface.
