All Implemented Interfaces:

java.lang.Runnable, java.util.concurrent.Future<java.lang.Exception>, java.util.concurrent.RunnableFuture<java.lang.Exception>

public class ParsingWorker
extends MidicaWorker

This class is used to parse a file (or URL) in the background while a WaitView is shown.

This worker is executed in the background before the (blocking) setVisible() method of the (modal) waiting dialog is called. That causes the execution of doInBackground() that parses the file or URL.

After the parsing work is finished, MidicaWorker.done() is called and closes the waiting dialog.
