- - ### Enum Constant Summary

    Enum Constants
    Enum Constant | Description
    --- | ---
    `EVENT_LOOP` | Tasks are scheduled on the event-loop thread of the vertx instance.
    `OTHER` | Tasks are scheduled on threads not managed by the current vertx instance, the nature of the thread is unknown to the vertx instance.
    `VIRTUAL_THREAD` | Tasks are scheduled on a virtual thread, no assumption on whether virtual threads are pooled.
    `WORKER` | Tasks are scheduled on a worker pool of platform threads managed by the vertx instance.

- - ### Enum Constant Detail

    - #### EVENT_LOOP

          public static final ThreadingModel EVENT_LOOP

      Tasks are scheduled on the event-loop thread of the vertx instance.

    - #### WORKER

          public static final ThreadingModel WORKER

      Tasks are scheduled on a worker pool of platform threads managed by the vertx instance.

    - #### VIRTUAL_THREAD

          public static final ThreadingModel VIRTUAL_THREAD

      Tasks are scheduled on a virtual thread, no assumption on whether virtual threads are pooled.

    - #### OTHER

          public static final ThreadingModel OTHER

      Tasks are scheduled on threads not managed by the current vertx instance, the nature of the thread is unknown to the vertx instance. Note that an event-loop thread of another vertx instance falls in this category.

  - ### Method Detail

    - #### values

          public static ThreadingModel[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (ThreadingModel c : ThreadingModel.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static ThreadingModel valueOf​(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
