WorkerExecutor (Vert.x Stack - Docs 5.0.0.CR3 API)

All Superinterfaces:

Measured
```
public interface WorkerExecutor
extends 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.

- Method Detail
  - executeBlocking
```
<T> Future<T> executeBlocking(Callable<T> blockingCodeHandler,
                              boolean ordered)
```
    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.
    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.
    
    Type Parameters:
    
    T - the type of the result
    
    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:
    
    a future notified with the result
  - executeBlocking
```
default <T> Future<T> executeBlocking(Callable<T> blockingCodeHandler)
```
    Like executeBlocking(Callable, boolean) called with ordered = true.
  - close
```
Future<Void> close()
```
    Close the executor.
