# RoutingContext 

###
Companion object RoutingContext

#### class RoutingContext extends AnyRef

Represents the context for the handling of a request in Vert.x-Web.

A new instance is created for each HTTP request that is received in the of the router.

The same instance is passed to any matching request or failure handlers during the routing of the request or failure.

The context provides access to the and and allows you to maintain arbitrary data that lives for the lifetime of the context. Contexts are discarded once they have been routed to the handler for the request.

The context also provides access to the io.vertx.scala.ext.web.Session, cookies and body for the request, given the correct handlers in the application.

If you use the internal error handler

4.  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

5.  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.

6.  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.

7.  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

8.  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.
