public interface IPluginAction<F>

A plugin Action.
The action should rely on a service instead of implementing the business rules itself if possible.

• fillModel(HttpServletRequest, AdminUser, Map) is called by the JspBean to add additionnal data in the main model
• getButtonTemplate() is used to display buttons.
• isInvoked(HttpServletRequest) is used by a JspBean to detect the invoked action.
• process(HttpServletRequest, HttpServletResponse, AdminUser, Object) is called by the JspBean to process the invoked action. The IPluginActionResult may contain html content or a redirect url or a noop as a result of the action processing.
• getName() is mainly for debbuging purpose
