io.vertx.ext.sync

## Class SyncVerticle

- java.lang.Object
- - io.vertx.core.AbstractVerticle
  - - io.vertx.ext.sync.SyncVerticle

- All Implemented Interfaces:
    Verticle

      public abstract class SyncVerticle
      extends AbstractVerticle

  A `Verticle` which runs its `start` and `stop` methods using fibers. You should subclass this class instead of `AbstractVerticle` to create any verticles that use vertx-sync.

          public SyncVerticle()

  - ### Method Detail

    - #### start

          public void start(Promise<Void> startFuture)
                     throws Exception

      Description copied from interface: `Verticle`
      Start the verticle instance.

      Vert.x calls this method when deploying the instance. You do not call it yourself.

      A promise is passed into the method, and when deployment is complete the verticle should either call `Promise.complete(T)` or `Promise.fail(java.lang.Throwable)` the future.

      Parameters:
        `startFuture` - the future
      Throws:
        `Exception`

    - #### stop

          public void stop(Promise<Void> stopFuture)
                    throws Exception

      Description copied from interface: `Verticle`
      Stop the verticle instance.

      Vert.x calls this method when un-deploying the instance. You do not call it yourself.

      A promise is passed into the method, and when un-deployment is complete the verticle should either call `Promise.complete(T)` or `Promise.fail(java.lang.Throwable)` the future.

      Parameters:
        `stopFuture` - the future
      Throws:
        `Exception`

    - #### start

          @Suspendable
          public void start()
                                  throws Exception

      Override this method in your verticle
      Overrides:
        `start` in class `AbstractVerticle`
      Throws:
        `Exception`

    - #### stop

          @Suspendable
          public void stop()
                                 throws Exception

      Optionally override this method in your verticle if you have cleanup to do
      Overrides:
        `stop` in class `AbstractVerticle`
      Throws:
        `Exception`
