java.lang.Object

ro.pippo.controller.ControllerHandler

All Implemented Interfaces:

RouteHandler

public class ControllerHandler
extends java.lang.Object
implements RouteHandler

It's a RouteHandler that executes the controller's methods. You can customize ContentTypeEngines, ControllerFactory, MethodParameterExtractors. By default, the MethodParameterExtractors are obtained via ServiceLoader. DefaultControllerFactory is used if a custom ControllerFactory is not supplied via ControllerHandler::setControllerFactory.
