/**
 * Callback that allows for initialization of a binder with
 * custom editors before kicking off the binding process.
 *
 * 

This is effectively a way to factor binder initialization out into * a dedicated object, to be invoked through BindUtils. In all other * respects, it is equivalent to the initBinder template * method defined by the BaseCommandController class. * * @author Jean-Pierre Pawlak * @since 08.05.2003 * @deprecated since Spring 1.2.7: prefer direct ServletRequestDataBinder usage, * potentially in combination with a PropertyEditorRegistrar * @see ServletRequestDataBinder * @see org.springframework.beans.PropertyEditorRegistrar */ public interface BindInitializer { /** * Initialize the given binder instance, e.g. with custom editors. * Called by BindUtils.bind. *

This method allows you to register custom editors for certain fields * of your command class. For instance, you will be able to transform Date * objects into a String pattern and back, in order to allow your JavaBeans * to have Date properties and still be able to set and display them in, * for instance, an HTML interface. * @param request current request * @param binder new binder instance * @throws ServletException in case of invalid state or arguments * @see org.springframework.validation.DataBinder#registerCustomEditor */ void initBinder(ServletRequest request, ServletRequestDataBinder binder) throws ServletException; }
