RarArchiveLoadOptions()

public RarArchiveLoadOptions()

getDecryptionPassword()

public final String getDecryptionPassword()

Hämtar lösenordet för att dekryptera poster och postnamn.

Du kan ange avkrypteringslösenordet en gång vid arkivextraktion.

try (FileInputStream fs = new FileInputStream(“encrypted_archive.rar”)) { try (FileOutputStream extracted = new FileOutputStream(“extracted.bin”)) { RarArchiveLoadOptions options = new RarArchiveLoadOptions(); options.setDecryptionPassword(“p@s$”); try (RarArchive archive = new RarArchive(fs, options)) { try (InputStream decompressed = archive.getEntries().get(0).open()) { byte[] b = new byte[8192]; int bytesRead; while (0 < (bytesRead = decompressed.read(b, 0, b.length))) extracted.write(b, 0, bytesRead); } } } } catch (IOException ex) { }




**Returns:**
java.lang.String - the password to decrypt entries and entry names.
### getDictionaryStorageMode() {#getDictionaryStorageMode--}

public final RarDictionaryStorageMode getDictionaryStorageMode()



Gets how the RAR decompression dictionary is stored.

**Returns:**
[RarDictionaryStorageMode](../../com.aspose.zip/rardictionarystoragemode) - the dictionary storage mode
### getTemporaryDirectory() {#getTemporaryDirectory--}

public final String getTemporaryDirectory()



Gets the directory used for temporary dictionary files.

**Returns:**
java.lang.String - the temporary directory; the system temporary directory is used by default
### setCancellationFlag(CancellationFlag value) {#setCancellationFlag-com.aspose.zip.CancellationFlag-}

public void setCancellationFlag(CancellationFlag value)



Sets a cancellation flag used to cancel the extraction operation.

Cancel RAR archive extraction after a certain time.


     try (CancellationFlag cf = new CancellationFlag()) {
         cf.cancelAfter(TimeUnit.SECONDS.toMillis(60));
         RarArchiveLoadOptions options = new RarArchiveLoadOptions();
         options.setCancellationFlag(cf);
         try (RarArchive a = new RarArchive("big.rar", options)) {
             try {
                 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. |

### setDecryptionPassword(String value) {#setDecryptionPassword-java.lang.String-}
