e4s.servlet
Class E4MethodRegistry

java.lang.Object
  e4s.util.E4Object
      e4s.servlet.E4MethodRegistry

public class E4MethodRegistry
extends E4Object

Registration of the callback functions. Your application consists of different modules, inheritated from E4ModuleImplementation. Each of this modules contains one or more function, and a public static member variable of class E4Method which is initially assigned with null. Now this module comes into the play: each module registerd, is interpreted and the E4Method becomes assigned a unique alias key (int). Based on this key, the CGI mechanism of the server/browser communicates and the e4s on the backend side can convert the alias key into instancing of your module, and calling your function providing possible parameters.

Since:

JDK 1.4
