def acceptableLanguages(): Buffer[LanguageHeader]

Returns the languages for the current request.

Returns the languages for the current request. The languages are determined from the Accept-Language header and sorted on quality.

When 2 or more entries have the same quality then the order used to return the best match is based on the lowest index on the original list. For example if a user has en-US and en-GB with same quality and this order the best match will be en-US because it was declared as first entry by the client. * @return The best matched language for the request

def acceptableLocales(): Buffer[Locale]

Returns the locales for the current request.

Returns the locales for the current request. The locales are determined from the accept-languages header and sorted on quality.

When 2 or more entries have the same quality then the order used to return the best match is based on the lowest index on the original list. For example if a user has en-US and en-GB with same quality and this order the best match will be en-US because it was declared as first entry by the client. * @return the best matched locale for the request

def addBodyEndHandler(handler: Handler[Unit]): Int

Provides a handler that will be called after the last part of the body is written to the wire.

Provides a handler that will be called after the last part of the body is written to the wire. The handler is called asynchronously of when the response has been received by the client. This provides a hook allowing you to do more operations once the request has been sent over the wire. Do not use this for resource cleanup as this handler might never get called (e.g. if the connection is reset). * @param handler the handler

returns: the id of the handler. This can be used if you later want to remove the handler.

def addCookie(cookie: Cookie): RoutingContext

Add a cookie.

Add a cookie. This will be sent back to the client in the response. The context must have first been routed to a io.vertx.scala.ext.web.handler.CookieHandler for this to work. * @param cookie the cookie

returns: a reference to this, so the API can be used fluently

def addHeadersEndHandler(handler: Handler[Unit]): Int

Add a handler that will be called just before headers are written to the response.

Add a handler that will be called just before headers are written to the response. This gives you a hook where you can write any extra headers before the response has been written when it will be too late. * @param handler the handler

returns: the id of the handler. This can be used if you later want to remove the handler.

def next(): Unit

Tell the router to route this context to the next matching route (if any).

Tell the router to route this context to the next matching route (if any). This method, if called, does not need to be called during the execution of the handler, it can be called some arbitrary time later, if required.

If next is not called for a handler then the handler should make sure it ends the response or no response will be sent.

def normalisedPath(): String

Return the normalised path for the request.

The normalised path is where the URI path has been decoded, i.e. any unicode or other illegal URL characters that were encoded in the original URL with % will be returned to their original form. E.g. %20 will revert to a space. Also + reverts to a space in a query.
