submitIfRunning

public Future<java.lang.Void> submitIfRunning(java.lang.Runnable task,
                                              java.lang.String name)

submitIfRunning

public <T> Future<T> submitIfRunning(java.util.concurrent.Callable<T> task,
                                     java.lang.String name)

Submit the task but only if the executor has not been shutdown.If the executor has been shutdown, or in case of a rejected execution exception return a cancelled future.

Parameters:

task - - the task to submit

name - - the task name to use in log messages

Returns:

the future that will deliver the task result, or a future that has already been cancelled if the task could not be submitted.
