22 /**
23 * A {@link org.apache.myfaces.orchestra.viewController.ViewControllerManager} implementation which uses
24 * annotations on backing beans to determine the beans responsible for a given view and execute
25 * the appropriate annotated methods.
26 *
27 * <p>When using Spring, every bean declaration in the spring config files is checked to see if the
28 * referenced class has annotations, and if so that information is cached. Here, that information is
29 * then used to locate a bean which has a ViewController annotation that references the current view.</p>
30 *
31 * <p>See also org.apache.myfaces.orchestra.viewController.annotations.*.</p>
32 *
33 * <p>
34 * Notice: For backward compatiblity with the Orchestra-core module this ViewControllerManager
35 * will take the Orchestra-core naming strategy
36 * into account and uses reflection if no annotated method were found.
37 * </p>
