# WorkerExecutor

interface WorkerExecutor(source)

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`.
