public interface UIRefreshHandler
extends UIComponent

Extension of UIComponent interface for complex components which contain other UIComponent-s. Components that implement this interface will not be refreshed recursively by framework logic (refresh of UIComponentContainer.getChildUIComponents() is not performed even if implementor implements the UIComponentContainer interface), but will need to handle initialization and refresh of their child components themselves (most commonly in the UIComponent.refresh() method).
