public NullProgressMonitor()
public void beginTask(String name, int totalWork)
beginTask in interface IProgressMonitorname - the name (or description) of the main tasktotalWork - the total number of work units into which
the main task is been subdivided. If the value is UNKNOWN
the implementation is free to indicate progress in a way which
doesn't require the total number of work units in advance.IProgressMonitor.beginTask(String, int)public void done()
done in interface IProgressMonitorIProgressMonitor.done()public void internalWorked(double work)
internalWorked in interface IProgressMonitorwork - the amount of work doneIProgressMonitor.internalWorked(double)public boolean isCanceled()
setCanceled.
