    `void` | Vertx.`deployVerticle(Verticle verticle, DeploymentOptions options, Handler<AsyncResult<String>> completionHandler)` Like `Vertx.deployVerticle(Verticle, Handler)` but `DeploymentOptions` are provided to configure the deployment.
    `void` | Vertx.`deployVerticle(Verticle verticle, Handler<AsyncResult<String>> completionHandler)` Like `Vertx.deployVerticle(Verticle)` but the completionHandler will be notified when the deployment is complete.

  - ### Uses of Verticle in io.vertx.core.spi

    `void` | VertxMetrics.`verticleUndeployed(Verticle verticle)` Called when a verticle is undeployed in Vert.x . This method is invoked with `Context` and thread of the deployed verticle and therefore might be different on every invocation, however these are the same than the `VertxMetrics.verticleDeployed(io.vertx.core.Verticle)` invocation.
