Description:
 def dispatch( self, view_func, path_info=None, method=None, catch_http_exceptions=False ):
 """Does the complete dispatching process. `view_func` is called with the endpoint and a dict with the values for the view. It should look up the view function, call it, and return a response object or WSGI application. http exceptions are not caught by default so that applications can display nicer error messages by just catching them by hand. If you want to stick with the default error messages you can pass it ``catch_http_exceptions=True`` and it will catch the http exceptions. Here a small example for the dispatch usage:: from werkzeug.wrappers import Request, Response from werkzeug.wsgi import responder from werkzeug.routing import Map, Rule def on_index(request):
 return Response('Hello from the index') url_map = Map([Rule('/', endpoint='index')]) views = {'index': on_index} @responder def application(environ, start_response):
 request = Request(environ) urls = url_map.bind_to_environ(environ) return urls.dispatch(lambda e, v: views[e](request, **v), catch_http_exceptions=True) Keep in mind that this method might return exception objects, too, so use :class:`Response.force_type` to get a response object. :param view_func: a function that is called with the endpoint as first argument and the value dict as second. Has to dispatch to the actual view function with this information. (see above) :param path_info: the path info to use for matching. Overrides the path info specified on binding. :param method: the HTTP method used for matching. Overrides the method specified on binding. :param catch_http_exceptions: set to `True` to catch any of the werkzeug :class:`HTTPException`\\s. """
