Metoder

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.
setExtractionProgressed(Event<ProgressEventArgs> value)Ställer in en händelse som utlöses när några byte har extraherats.

Bzip2LoadOptions()

public Bzip2LoadOptions()

getExtractionProgressed()

public Event<ProgressEventArgs> getExtractionProgressed()

Hämtar en händelse som utlöses när några byte har extraherats.

int[] percent = { 0 }; long originalFileLength = 10_000_000;

Bzip2LoadOptions loadOptions = new Bzip2LoadOptions(); loadOptions.setExtractionProgressed((sender, args) -> { percent[0] = (int)((100 * (double)args.getProceededBytes()) / originalFileLength); });


Event sender is the [Bzip2Archive](../../com.aspose.zip/bzip2archive) instance which extraction is progressed. The `ProgressEventArgs.getProceededBytes()`([ProgressEventArgs.getProceededBytes()](../../com.aspose.zip/progresseventargs\#getProceededBytes--)) is the number of bytes after extraction.

**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 Bzip2 archive extraction after a certain time.


     try (CancellationFlag cf = new CancellationFlag()) {
         cf.cancelAfter(TimeUnit.SECONDS.toMillis(60));
         Bzip2LoadOptions options = new Bzip2LoadOptions();
         options.setCancellationFlag(cf);
         try (Bzip2Archive a = new Bzip2Archive("big.bz2", 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--}
```
public void setExtractionProgressed(Event<ProgressEventArgs> value)
```


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

```

int[] percent = { 0 }; long originalFileLength = 10_000_000;

Bzip2LoadOptions loadOptions = new Bzip2LoadOptions(); loadOptions.setExtractionProgressed((sender, args) -> { percent[0] = (int)((100 * (double)args.getProceededBytes()) / originalFileLength); });


Event sender is the [Bzip2Archive](../../com.aspose.zip/bzip2archive) instance which extraction is progressed. The `ProgressEventArgs.getProceededBytes()`([ProgressEventArgs.getProceededBytes()](../../com.aspose.zip/progresseventargs\#getProceededBytes--)) is the number of bytes after extraction.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | com.aspose.zip.Event&lt;com.aspose.zip.ProgressEventArgs&gt; | an event that is raised when some bytes have been extracted |
