to null, if the task should create, open, and close a progress monitor.
Set progressMonitor to NullProgressMonitor.INSTANCE
if progress information is to
be discarded.
You can wait for the asynchronous download task to finish by synchronizing on the returned
Future
, but make sure not to freeze up JOSM. Example:
Future<?> future = task.download(...); // DON'T run this on the Swing EDT or JOSM will freeze future.get(); // waits for the dowload task to completeThe following example uses a pattern which is better suited if a task is launched from the Swing EDT:
final Future<?> future = task.download(...); Runnable runAfterTask = new Runnable() { public void run() { // this is not strictly necessary because of the type of executor service // Main.worker is initialized with, but it doesn't harm either // future.get(); // wait for the download task to complete doSomethingAfterTheTaskCompleted(); } } Main.worker.submit(runAfterTask);
