Hi everyone,<br><br>Lee & I discussed a bit in the ImageJDev chat room, but for the benefit of the list archives: this was done in several of today's commits: <a href="http://dev.imagejdev.org/trac/imagej/changeset/3682">r3682</a>, <a href="http://dev.imagejdev.org/trac/imagej/changeset/3683">r3683</a>, <a href="http://dev.imagejdev.org/trac/imagej/changeset/3684">r3684</a>, <a href="http://dev.imagejdev.org/trac/imagej/changeset/3685">r3685</a>, <a href="http://dev.imagejdev.org/trac/imagej/changeset/3686">r3686</a> and <a href="http://dev.imagejdev.org/trac/imagej/changeset/3687">r3687</a>.<br>

Hi Curtis, all,<br>
I'm looking at ModuleService.run and thinking of how to use it in CellProfiler. There's a comment:<br>
// TODO - Implement a better threading mechanism for launching modules.<br>
// Perhaps a ThreadService so that the UI can query currently<br>
// running modules and so forth?<br>
<br>
which is pretty relevant. I think that the natural thing to do would be to return java.util.concurrent.Future<<u></u>Map<String, Object>> which would be a future promising the map of outputs for the module. You'd wrap the ModuleRunner in a java.util.concurrent.Callable<<u></u>Map<String, Object>> instead of in a Runnable and use java.util.concurrent.<u></u>FutureTask to return the future.<br>
<br>
I like a programmatic style myself where you do things step-by-step instead of an event-driven style like a ThreadService. This would be great for scripting - you can imagine a script that executes a module, then, further down, gets the results from the execution. The script would proceed in parallel with the module execution and the additional boilerplate for threading would be minimal - just an additional call to Future.get() at the point where the result was needed.<br>
