Also if you use ERXExecutorService to execute any Plain Old Java Callable (or
Runnable), your editing contexts will be auto unlocked by safety-net unlocker
at the end of execution if you haven't done so ....... however it is highly
recommend that you follow the ec lock/try/finally/unlock pattern in in your
Callable.call() or Runnable.run() methods anyway which will be better for long
running tasks, recycling ec's if needed, etc. it doesn't hurt.
EOEditingContext ec = ERXEC.newEditingContext();
ec.lock();
try {
........
} finally {
ec.unlock();
}
And yeah, do what Ramsey said .... save yourself time figuring out concurrency
management of EC's, etc. by watching the WOWODC presentation from 2011. There
is a bunch of stuff related to this in Wonder to make life in the background
easy and totally painless for you and that WOWODC session explains it's usage.
