        the number of instances

    - #### setInstances

          public DeploymentOptions setInstances​(int instances)

      Parameters:
        `instances` - the number of instances

    - #### getWorkerPoolName

          public String getWorkerPoolName()

      Returns:
        the worker pool name

    - #### setWorkerPoolName

          public DeploymentOptions setWorkerPoolName​(String workerPoolName)

      Set the worker pool name to use for this verticle. When no name is set, the Vert.x worker pool will be used, when a name is set, the verticle will use a named worker pool.
      Parameters:
        `workerPoolName` - the worker pool name
      Returns:
        a reference to this, so the API can be used fluently

    - #### getWorkerPoolSize

          public int getWorkerPoolSize()

      Get the maximum number of worker threads to be used by the worker pool when the verticle is deployed with a `setWorkerPoolName(java.lang.String)`.

      Worker threads are used for running blocking code and worker verticles.

      When the verticle does not use a `named worker pool`, this option has no effect.

      Returns:
        the maximum number of worker threads

    - #### setWorkerPoolSize

          public DeploymentOptions setWorkerPoolSize​(int workerPoolSize)

      Set the maximum number of worker threads to be used by the Vert.x instance.

      When the verticle does not use a `named worker pool`, this option has no effect.

      Parameters:
        `workerPoolSize` - the number of threads
      Returns:
        a reference to this, so the API can be used fluently

    - #### getMaxWorkerExecuteTime

          public long getMaxWorkerExecuteTime()

      Get the value of max worker execute time, in `maxWorkerExecuteTimeUnit`.

      Vert.x will automatically log a warning if it detects that worker threads haven't returned within this time.

      This can be used to detect where the user is blocking a worker thread for too long. Although worker threads can be blocked longer than event loop threads, they shouldn't be blocked for long periods of time.

      When the verticle does not use a `named worker pool`, this option has no effect.

      Returns:
        The value of max worker execute time, the default value of `setMaxWorkerExecuteTimeUnit(java.util.concurrent.TimeUnit)` `maxWorkerExecuteTimeUnit` is `TimeUnit.NANOSECONDS`

    - #### setMaxWorkerExecuteTime

          public DeploymentOptions setMaxWorkerExecuteTime​(long maxWorkerExecuteTime)

      Sets the value of max worker execute time, in `maxWorkerExecuteTimeUnit`.

      The default value of `maxWorkerExecuteTimeUnit` is `TimeUnit.NANOSECONDS`

      When the verticle does not use a `named worker pool`, this option has no effect.

      Parameters:
        `maxWorkerExecuteTime` - the value of max worker execute time, in in `maxWorkerExecuteTimeUnit`.
      Returns:
        a reference to this, so the API can be used fluently

    - #### getMaxWorkerExecuteTimeUnit

          public TimeUnit getMaxWorkerExecuteTimeUnit()

      When the verticle does not use a `named worker pool`, this option has no effect.
      Returns:
        the time unit of `maxWorkerExecuteTime`

    - #### setMaxWorkerExecuteTimeUnit

          public DeploymentOptions setMaxWorkerExecuteTimeUnit​(TimeUnit maxWorkerExecuteTimeUnit)

      Set the time unit of `maxWorkerExecuteTime`

      When the verticle does not use a `named worker pool`, this option has no effect.

      Parameters:
        `maxWorkerExecuteTimeUnit` - the time unit of `maxWorkerExecuteTime`
      Returns:
        a reference to this, so the API can be used fluently

    - #### getClassLoader

          public ClassLoader getClassLoader()

      Returns:
        the classloader used for deploying the Verticle

    - #### setClassLoader

          public DeploymentOptions setClassLoader​(ClassLoader classLoader)

      Set the classloader to use for deploying the Verticle.

      The `VerticleFactory` will use this classloader for creating the Verticle and the Verticle `Context` will set this classloader as context classloader for the tasks execution on context.

      By default no classloader is required and the deployment will use the current thread context classloader.

      Parameters:
        `classLoader` - the loader to use
      Returns:
        a reference to this, so the API can be used fluently
