Class RoutingContext


  • public class RoutingContext
    extends Object
    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 Handler 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 Session, cookies and body for the request, given the correct handlers in the application.

    If you use the internal error handler

    NOTE: This class has been automatically generated from the original non Mutiny-ified interface using Vert.x codegen.

        This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).

        Returns:
        the Void instance produced by the operation.
      • endAndForget

        public RoutingContext endAndForget()
        Variant of end(java.lang.String) that ignores the result of the operation.

        This method subscribes on the result of end(java.lang.String), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from end(java.lang.String) but you don't need to compose it with other operations.

        Returns:
        the instance of RoutingContext to chain method calls.
      • data

        public Map<String,​Object> data()
        Returns:
        all the context data as a map
      • queryParams

        public MultiMap queryParams​(Charset encoding)
        Parameters:
        encoding - a non null character set.
        Returns:
        the multimap of query parameters
      • lastModified

        public RoutingContext lastModified​(Instant instant)
        Parameters:
        instant - the last modified instant
        Returns:
        the instance of RoutingContext to chain method calls.
      • newInstance

        public static RoutingContext newInstance​(io.vertx.ext.web.RoutingContext arg)
