## Class WorkerExecutor

- java.lang.Object
- - io.vertx.rxjava3.core.WorkerExecutor

- All Implemented Interfaces:
    Measured

      public class WorkerExecutor
      extends Object
      implements Measured

  An executor for executing blocking code in Vert.x .

  It provides the same `executeBlocking` operation than `Context` and `Vertx` but on a separate worker pool.

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.

    - #### executeBlocking

          @Deprecated
          public <T> Maybe<T> executeBlocking(Handler<Promise<T>> blockingCodeHandler,
                                                          boolean ordered)

      Deprecated.
      Safely execute some blocking code.

      Executes the blocking code in the handler `blockingCodeHandler` using a thread from the worker pool.

      The returned future will be completed with the result on the original context (i.e. on the original event loop of the caller) or failed when the handler throws an exception.

      A `Future` instance is passed into `blockingCodeHandler`. When the blocking code successfully completes, the handler should call the `Promise.complete(T)` or `Promise.complete(T)` method, or the `Promise.fail(java.lang.Throwable)` method if it failed.

      In the `blockingCodeHandler` the current context remains the original context and therefore any task scheduled in the `blockingCodeHandler` will be executed on this context and not on the worker thread.

      Parameters:
        `blockingCodeHandler` - handler representing the blocking code to run
        `ordered` - if true then if executeBlocking is called 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:

    - #### rxExecuteBlocking

          @Deprecated
          public <T> Maybe<T> rxExecuteBlocking(Handler<Promise<T>> blockingCodeHandler,
