Class MessageManager

java.lang.Object

org.silverpeas.core.notification.message.MessageManager

public class MessageManager
extends Object

This manager provides tools to register and restitute volatile messages (info, success or error) to the user (on screen).

It works for now with Thread Cache Service, and several steps have to be performed : - use the initialize function in order to render accessible message tools provided - user message tools in treatment when necessary - use the destroy function in order to clear all message data attached to the thread

A typical initialization/destruction in a the service method of a HttpServlet : protected void service(HttpHttpServletResponse response) { MessageManager.initialize(); try { ... } finally { MessageManager.destroy(); ... } }

A typical use anywhere in treatments : if ([test of functionnal information is not ok]) { MessageMessager.addError(bundle.getMessage("err.label", params)); }
