MVP可以跟MVC对照起来看。和MVC一样，MVP的M就是 Model, V就是View，而P，则代表Presenter，它与Controller有点相似。
In this formulation, when a user triggers an event method of the view, it does nothing but invoke a method of the presenter which has no parameters and no return value. The presenter then retrieves data from the view through methods defined by the view interface. Finally, the presenter then operates on the model and updates the view with the results of the operation.
In a Java
(AWT/Swing/SWT) application, the MVP pattern can be used by letting the UI class implement a view interface.
The same approach can be used for Java thin (web based) applications since modern Java Component Based Web Frameworks allow development of client side logic using the same component approach as thick clients. To implement MVP in
Google Web Toolkit one just needs to let any component implement the view interface. The same approach is possible using the
Echo2 web framework.
