public abstract class AbstractObjectFolder<T>
extends Folder

This is wrapper class for introspectable objects. You have to give it object to be introspected in the constructor and implement methods computing array of properties and array of children objects (computeProperties() and computeChildren()). This abstract implementation caches computed results and returns them by getProperties() and getChildren() methods.
