public DownloadTask(DownloadParams settings,
                    OsmServerReader reader,
                    ProgressMonitor progressMonitor,
                    boolean zoomAfterDownload,
                    Compression compression)

Constructs a new DownloadTask.

Parameters:

settings - download settings

reader - OSM data reader

progressMonitor - progress monitor

zoomAfterDownload - If true, the map view will zoom to download area after download

compression - compression to use

Method Detail

parseDataSet

protected DataSet parseDataSet()
                        throws OsmTransferException

Overrides:

parseDataSet in class DownloadOsmTask.DownloadTask

Throws:

OsmTransferException

realRun

public void realRun()
             throws java.io.IOException,
                    org.xml.sax.SAXException,
                    OsmTransferException

Description copied from class: PleaseWaitRunnable

Called in the worker thread to do the actual work. When any of the exception is thrown, a message box will be displayed and closeDialog is called. finish() is called in any case.

Overrides:

realRun in class DownloadOsmTask.DownloadTask

Throws:

java.io.IOException - if an I/O error occurs

org.xml.sax.SAXException - if a SAX error occurs

OsmTransferException - if a communication error with the OSM server occurs

loadLastVersions

private void loadLastVersions(java.util.Map<OsmPrimitive,java.time.Instant> toLoad,
                              java.util.Map<OsmPrimitive,java.time.Instant> toLoadNext)
                       throws OsmTransferException

This gets the last versions of references primitives. This may enough for many of the primitives.

Parameters:

toLoad - The primitives to load

toLoadNext - The primitives to load next (filled by this method)

Throws:

OsmTransferException

finish

protected void finish()

Description copied from class: PleaseWaitRunnable

Finish up the data work. Is guaranteed to be called if realRun is called. Finish is called in the gui thread just after the dialog disappeared.

Overrides:

finish in class DownloadOsmTask.DownloadTask
