Interface ProcessExecutor

All Superinterfaces:

Executor, ExecutorService

All Known Implementing Classes:

ThreadPoolProcessExecutor

public interface ProcessExecutor
extends ExecutorService

An Executor that provides methods to manage termination and methods that can produce a Progress for tracking one or more asynchronous tasks.

Method submit extends base method ExecutorService.submit(java.util.concurrent.Callable<T>) by creating and returning a Progress that can be used to track how a process is doing in addition to cancelling execution and/or waiting for completion.

Method Detail

submit

Progress submit(Process task,
                Map<String,Object> input)

Submits a process for execution and returns a Progress representing the pending results of the task.

If you would like to immediately block waiting for a task, you can use constructions of the form result = exec.submit(aProcess).get();

Note: The Processors class includes a set of methods that can convert some other common closure-like objects, for example, Callable to Process form so they can be submitted.

Parameters:

task - the task to submit

Returns:

a Progress representing pending completion of the task

Throws:

RejectedExecutionException - if task cannot be scheduled for execution

NullPointerException - if task null
