WorkerExecutor (Gradle API 7.6.2)

```
public interface WorkerExecutor
```
Allows work to be submitted for asynchronous execution. This api allows for safe, concurrent execution of work items and enables:
- Parallel execution of work items within a single task
- Execution in isolated contexts such as an isolated classloader or even a separate process
- Safe execution of multiple tasks in parallel
Work should be submitted with a WorkAction class representing the implementation of the unit of work and an action to configure the parameters of the unit of work (via WorkParameters).
```
      workerExecutor.noIsolation().submit(MyWorkActionImpl.class) { MyWorkParameters parameters ->
          parameters.inputFile = project.file('foo')
          parameters.outputFile = project.layout.buildDirectory.file('bar')
      }
 
```
An instance of the executor can be injected into a task by annotating a public constructor or property getter method with javax.inject.Inject.

Modifier and Type	Method	Description
`void`	`await()`	Blocks until all work associated with the current build operation is complete.
`WorkQueue`	`classLoaderIsolation()`	Creates a `WorkQueue` to submit work for asynchronous execution with an isolated classloader.

@Deprecated
void submit(java.lang.Class<? extends java.lang.Runnable> actionClass,
            Action<? super WorkerConfiguration> configAction)
```
    Deprecated.
    
    Submits a piece of work to be executed asynchronously. Execution of the work may begin immediately. Work configured with IsolationMode.PROCESS will execute in an idle daemon that meets the requirements set in the WorkerConfiguration. If no idle daemons are available, a new daemon will be started. Any errors will be thrown from await() or from the surrounding task action if await() is not used.
  - noIsolation
```
WorkQueue noIsolation()
```
    Creates a WorkQueue to submit work for asynchronous execution with no isolation.
    
    Since:
    
    5.6
  - classLoaderIsolation
```
WorkQueue classLoaderIsolation()
```
    Creates a WorkQueue to submit work for asynchronous execution with an isolated classloader.
    
    Since:
    
    5.6
  - processIsolation
```
WorkQueue processIsolation()
```
    Creates a WorkQueue to submit work for asynchronous execution in a daemon process. Work will execute in an idle daemon, if available. If no idle daemons are available, a new daemon will be started.
    
    Since:
    
    5.6
  - noIsolation
```
WorkQueue noIsolation(Action<? super WorkerSpec> action)
```
    Creates a WorkQueue to submit work for asynchronous execution with no isolation and the requirements specified in the supplied WorkerSpec.
    
    Since:
    
    5.6
  - classLoaderIsolation
```
WorkQueue classLoaderIsolation(Action<? super ClassLoaderWorkerSpec> action)
```
    Creates a WorkQueue to submit work for asynchronous execution with an isolated classloader and the requirements specified in the supplied ClassLoaderWorkerSpec.
    
    Since:
    
    5.6
  - processIsolation
```
WorkQueue processIsolation(Action<? super ProcessWorkerSpec> action)
```
    Creates a WorkQueue to submit work for asynchronous execution in a daemon process. Work will execute in an idle daemon matching the requirements specified in the supplied ProcessWorkerSpec, if available. If no idle daemons are available, a new daemon will be started.
    
    Since:
    
    5.6
  - await
```
void await()
    throws WorkerExecutionException
```
    Blocks until all work associated with the current build operation is complete. Note that when using this method inside a task action, it will block completion of the task action until all submitted work is complete. This means that other tasks from the same project cannot be run in parallel while the task action is still executing.
    
    Throws:
    
    WorkerExecutionException - when a failure occurs while executing the work.
