MetodBeskrivning
getExtractionProgressed()Hämtar en händelse som utlöses när några byte har extraherats.
setCancellationFlag(CancellationFlag value)Ställer in en avbrytningsflagga som används för att avbryta extraheringsoperationen.

ZstandardLoadOptions()

public ZstandardLoadOptions()

getExtractionProgressed()

public Event<ProgressEventArgs> getExtractionProgressed()

Hämtar en händelse som utlöses när några byte har extraherats.

long length = 10_000_000; ZStandardLoadOptions loadOptions = new ZStandardLoadOptions(); loadOptions.setExtractionProgressed((sender, args) -> { int percent = (int)((100 * args.getProceededBytes()) / length); }); ZstandardArchive archive = new ZstandardArchive(“archive.zst”, loadOptions);


Event sender is the [ZstandardArchive](../../com.aspose.zip/zstandardarchive) 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 Zstandard archive extraction after a certain time.


     try (CancellationFlag cf = new CancellationFlag()) {
         cf.cancelAfter(TimeUnit.SECONDS.toMillis(60));
         ZstandardLoadOptions options = new ZstandardLoadOptions();
         options.setCancellationFlag(cf);
         try (ZstandardArchive a = new ZstandardArchive("big.zstd", options)) {
             try {
                 a.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. |

### setExtractionProgressed(Event&lt;ProgressEventArgs&gt; value) {#setExtractionProgressed-com.aspose.zip.Event-com.aspose.zip.ProgressEventArgs--}
