MetodBeskrivning

setCancellationFlag(CancellationFlag value)Ställer in en avbrytningsflagga som används för att avbryta extraheringsoperationen.

XarLoadOptions()

public XarLoadOptions()

getEntryExtractionProgressed()

public final Event<ProgressEventArgs> getEntryExtractionProgressed()

Hämtar en händelse som utlöses när några byte har extraherats.

XarLoadOptions loadOptions = new XarLoadOptions(); loadOptions.setEntryExtractionProgressed((sender, args) -> { int percent = (int)((100 * args.getProceededBytes()) / ((XarFileEntry)sender).getLength()); }); XarArchive archive = new XarArchive(“archive.xar”, loadOptions);


Event sender is the [XarFileEntry](../../com.aspose.zip/xarfileentry) instance which extraction is progressed.

**Returns:**
[Event](../../com.aspose.zip/event) - an event that is raised when some bytes have been extracted
### setCancellationFlag(CancellationFlag value) {#setCancellationFlag-com.aspose.zip.CancellationFlag-}

public void setCancellationFlag(CancellationFlag value)



Sets a cancellation flag used to cancel the extraction operation.

Cancel XAR archive extraction after a certain time.


     try (CancellationFlag cf = new CancellationFlag()) {
         cf.cancelAfter(TimeUnit.SECONDS.toMillis(60));
         XarLoadOptions options = new XarLoadOptions();
         options.setCancellationFlag(cf);
         try (XarArchive a = new XarArchive("big.xar", options)) {
             try {
                 ((XarFileEntry) a.getEntries().get(0)).extract("data.bin");
             } catch (OperationCanceledException e) {
                 System.out.println("Extraction was cancelled after 60 seconds");
             }
         }
     }
 
```

Avbrytning resulterar oftast i att vissa data inte extraheras.

**Parameters:**
| Parameter | Typ | Beskrivning |
| --- | --- | --- |
| value | [CancellationFlag](../../com.aspose.zip/cancellationflag) | en avbrytande flagga som används för att avbryta extraktionsoperationen. |

### setEntryExtractionProgressed(Event&lt;ProgressEventArgs&gt; value) {#setEntryExtractionProgressed-com.aspose.zip.Event-com.aspose.zip.ProgressEventArgs--}
```
public final void setEntryExtractionProgressed(Event<ProgressEventArgs> value)
```


Ställer in en händelse som utlöses när några byte har extraherats.

```

Event sender is the [XarFileEntry](../../com.aspose.zip/xarfileentry) instance which extraction is progressed.

**Parameters:**
