    Modifier and Type | Method and Description
    --- | ---
    `static Scheduler` | `blockingScheduler(Vertx vertx)` Create a scheduler for a `Vertx` object, actions can be blocking, they are not executed on Vertx event loop.
    `static Scheduler` | `blockingScheduler(Vertx vertx, boolean ordered)` Create a scheduler for a `Vertx` object, actions can be blocking, they are not executed on Vertx event loop.
    `static Observable<String>` | `deployVerticle(Vertx vertx, Verticle verticle)` Deploy a verticle you have created yourself, using an RxJava vertx instance.
    `static Observable<String>` | `deployVerticle(Vertx vertx, Verticle verticle, DeploymentOptions options)` Like `deployVerticle(Vertx, Verticle)`, but `DeploymentOptions` are provided to configure the deployment.
    `static Scheduler` | `scheduler(Context context)` Create a scheduler for a `Context`, actions are executed on the event loop of this context.
    `static Scheduler` | `scheduler(Vertx vertx)` Create a scheduler for a `Vertx` object, actions are executed on the event loop of the current context.
    `static Scheduler` | `scheduler(WorkerExecutor executor)` Create a scheduler for a `WorkerExecutor` object, actions are executed on the threads of this executor.
    `static RxJavaSchedulersHook` | `schedulerHook(Context context)` Create a scheduler hook for a `Context` object.
    `static RxJavaSchedulersHook` | `schedulerHook(Vertx vertx)` Create a scheduler hook for a `Vertx` object.
    `static <T> Observable.Operator<T,Buffer>` | `unmarshaller(Class<T> mappedType)` Returns a json unmarshaller for the specified java type as a `Observable.Operator` instance. The marshaller can be used with the `Observable.lift(rx.Observable.Operator)` method to transform a Observable<Buffer> into a Observable<T>. The unmarshaller buffers the content until onComplete is called, then unmarshalling happens. Note that the returned observable will emit at most a single object.

  - ### Method Detail

    - #### schedulerHook

          public static RxJavaSchedulersHook schedulerHook(Vertx vertx)

      Create a scheduler hook for a `Vertx` object.
      Parameters:
        `vertx` - the vertx object
      Returns:
        the scheduler hook

    - #### schedulerHook

          public static RxJavaSchedulersHook schedulerHook(Context context)

      Create a scheduler hook for a `Context` object.
      Parameters:
        `context` - the context object
      Returns:
        the scheduler hook

    - #### scheduler

          public static Scheduler scheduler(Vertx vertx)

      Create a scheduler for a `Vertx` object, actions are executed on the event loop of the current context.
      Parameters:
        `vertx` - the vertx object
      Returns:
        the scheduler

    - #### scheduler

          public static Scheduler scheduler(WorkerExecutor executor)

      Create a scheduler for a `WorkerExecutor` object, actions are executed on the threads of this executor.
      Parameters:
        `executor` - the worker executor object
      Returns:
        the scheduler

    - #### scheduler

          public static Scheduler scheduler(Context context)

      Create a scheduler for a `Context`, actions are executed on the event loop of this context.
      Parameters:
        `context` - the context object
      Returns:
        the scheduler

    - #### blockingScheduler

          public static Scheduler blockingScheduler(Vertx vertx)

      Create a scheduler for a `Vertx` object, actions can be blocking, they are not executed on Vertx event loop.
      Parameters:
        `vertx` - the vertx object
      Returns:
        the scheduler

    - #### blockingScheduler

          public static Scheduler blockingScheduler(Vertx vertx,
                                                    boolean ordered)

      Create a scheduler for a `Vertx` object, actions can be blocking, they are not executed on Vertx event loop.
      Parameters:
        `vertx` - the vertx object
        `ordered` - if true then if when tasks are scheduled several times on the same context, the executions for that context will be executed serially, not in parallel. if false then they will be no ordering guarantees
      Returns:
        the scheduler

    - #### unmarshaller

          public static <T> Observable.Operator<T,Buffer> unmarshaller(Class<T> mappedType)

      Returns a json unmarshaller for the specified java type as a `Observable.Operator` instance.

      The marshaller can be used with the `Observable.lift(rx.Observable.Operator)` method to transform a Observable<Buffer> into a Observable<T>.

      The unmarshaller buffers the content until onComplete is called, then unmarshalling happens.

      Note that the returned observable will emit at most a single object.
      Parameters:
        `mappedType` - the type to unmarshall
      Returns:
        the unmarshaller operator

    - #### deployVerticle

          public static Observable<String> deployVerticle(Vertx vertx,
                                                          Verticle verticle)

      Deploy a verticle you have created yourself, using an RxJava vertx instance.
      Parameters:
        `vertx` - the vertx instance
        `verticle` - the verticle instance to deploy
      Returns:
        the response observable

    - #### deployVerticle

          public static Observable<String> deployVerticle(Vertx vertx,
                                                          Verticle verticle,
                                                          DeploymentOptions options)

      Like `deployVerticle(Vertx, Verticle)`, but `DeploymentOptions` are provided to configure the deployment.
      Parameters:
        `vertx` - the vertx instance
        `verticle` - the verticle instance to deploy
        `options` - the deployment options.
      Returns:
        the response observable
