## Class Route

- java.lang.Object
- - io.vertx.reactivex.ext.web.Route

-     public class Route
      extends Object

  A route is a holder for a set of criteria which determine whether an HTTP request or failure should be routed to a handler.

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

    - #### handler

          public Route handler(Handler<RoutingContext> requestHandler)

      Append a request handler to the route handlers list. The router routes requests to handlers depending on whether the various criteria such as method, path, etc match. When method, path, etc are the same for different routes, You should add multiple handlers to the same route object rather than creating two different routes objects with one handler for route
      Parameters:
        `requestHandler` - the request handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### blockingHandler

          public Route blockingHandler(Handler<RoutingContext> requestHandler)

      Like `blockingHandler(io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>)` called with ordered = true
      Parameters:
        `requestHandler` -
      Returns:

    - #### subRouter

          public Route subRouter(Router subRouter)

      Use a (sub) `Router` as a handler. There are several requirements to be fulfilled for this to be accepted.
      - The route path must end with a wild card
      - Parameters are allowed but full regex patterns not
      - No other handler can be registered before or after this call (but they can on a new route object for the same path)
      - Only 1 router per path object
      Parameters:
        `subRouter` - the router to add
      Returns:
        a reference to this, so the API can be used fluently

    - #### blockingHandler

          public Route blockingHandler(Handler<RoutingContext> requestHandler,
                                       boolean ordered)

      Specify a blocking request handler for the route. This method works just like `handler(io.vertx.core.Handler<io.vertx.reactivex.ext.web.RoutingContext>)` excepted that it will run the blocking handler on a worker thread so that it won't block the event loop. Note that it's safe to call context.next() from the blocking handler as it will be executed on the event loop context (and not on the worker thread.

      If the blocking handler is ordered it means that any blocking handlers for the same context are never executed concurrently but always in the order they were called. The default value of ordered is true. If you do not want this behaviour and don't mind if your blocking handlers are executed in parallel you can set ordered to false.

      Parameters:
        `requestHandler` - the blocking request handler
        `ordered` - if true handlers are executed in sequence, otherwise are run in parallel
      Returns:
        a reference to this, so the API can be used fluently

    - #### failureHandler

          public Route failureHandler(Handler<RoutingContext> failureHandler)

      Append a failure handler to the route failure handlers list. The router routes failures to failurehandlers depending on whether the various criteria such as method, path, etc match. When method, path, etc are the same for different routes, You should add multiple failure handlers to the same route object rather than creating two different routes objects with one failure handler for route
      Parameters:
        `failureHandler` - the request handler
      Returns:
        a reference to this, so the API can be used fluently

    - #### remove

          public Route remove()

      Remove this route from the router
      Returns:
        a reference to this, so the API can be used fluently

    - #### disable

          public Route disable()

      Disable this route. While disabled the router will not route any requests or failures to it.

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

    - #### enable

          public Route enable()

      Enable this route.
      Returns:
        a reference to this, so the API can be used fluently

      Returns:

    - #### useNormalizedPath

          public Route useNormalizedPath(boolean useNormalizedPath)

      Parameters:
        `useNormalizedPath` - use normalized path for routing?
      Returns:
        a reference to this, so the API can be used fluently

    - #### setRegexGroupsNames

          public Route setRegexGroupsNames(List<String> groups)

      When you add a new route with a regular expression, you can add named capture groups for parameters.
      However, if you need more complex parameters names (like "param_name"), you can add parameters names with this function. You have to name capture groups in regex with names: "p0", "p1", "p2", ...
      For example: If you declare route with regex \/(?[a-z]*)\/(?[a-z]*) and group names ["param_a", "param-b"] for uri /hello/world you receive inside pathParams() the parameter param_a = "hello"
      Parameters:
        `groups` - group names
      Returns:
        a reference to this, so the API can be used fluently

    - #### setName

          public Route setName(String name)

      Giving a name to a route will provide this name as metadata to requests matching this route. This metadata is used by metrics and is meant to group requests with different URI paths (due to parameters) by a common identifier, for example "/resource/:resourceID" common name
      Parameters:
        `name` - The name of the route.
      Returns:
        a reference to this, so the API can be used fluently

    - #### getName

          public String getName()

      Returns:
        the name of the route. If not given explicitly, the path or the pattern or null is returned (in that order)

    - #### respond

          public <T> Route respond(java.util.function.Function<RoutingContext,Future<T>> function)

      Append a function request handler to the route handlers list. The function expects to receive the routing context and users are expected to return a . The use of this functional interface allows users to quickly link the responses from other vert.x APIs or clients directly to a handler. If the context response has been ended, for example, `RoutingContext.end(java.lang.String, io.vertx.core.Handler<io.vertx.core.AsyncResult<java.lang.Void>>)` has been called, then nothing shall happen. For the remaining cases, the following rules apply:
      1. When `body` is `null` then the status code of the response shall be 204 (NO CONTENT)
      2. When `body` is of type and the `Content-Type` isn't set then the `Content-Type` shall be `application/octet-stream`
      3. When `body` is of type `String` and the `Content-Type` isn't set then the `Content-Type` shall be `text/html`
      4. Otherwise the response of the future is then passed to the method `RoutingContext.json(java.lang.Object, io.vertx.core.Handler<io.vertx.core.AsyncResult<java.lang.Void>>)` to perform a JSON serialization of the result
      Internally the function is wrapped as a handler that handles error cases for the user too. For example, if the function throws an exception the error will be catched and a proper error will be propagated throw the router. Also if the same happens while encoding the response, errors are catched and propagated to the router.
      Parameters:
        `function` - the request handler function
      Returns:
        a reference to this, so the API can be used fluently

    - #### respond

          public <T> Route respond(Function<RoutingContext,Maybe<T>> function)

      Append a function request handler to the route handlers list. The function expects to receive the routing context and users are expected to return a . The use of this functional interface allows users to quickly link the responses from other vert.x APIs or clients directly to a handler.
