### SnappyArchive() {#SnappyArchive--}
```
public SnappyArchive()
```


Initierar en ny instans av klassen [SnappyArchive](../../com.aspose.zip/snappyarchive) för komprimering.

Följande exempel visar hur man komprimerar en fil.

```

``````

try (SnappyArchive archive = new SnappyArchive()) {
archive.setSource("data.bin");
archive.save(\"archive.snappy\");
}
 
```



### SnappyArchive(InputStream source) {#SnappyArchive-java.io.InputStream-}
```
public SnappyArchive(InputStream source)
```


Initializes a new instance of the [SnappyArchive](../../com.aspose.zip/snappyarchive) class prepared for decompressing.

This constructor does not decompress. See [extract(java.io.OutputStream)](../../com.aspose.zip/snappyarchive\#extract-java.io.OutputStream-) method for decompressing.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| source | java.io.InputStream | The source of the archive. |

### SnappyArchive(String path) {#SnappyArchive-java.lang.String-}
```
public SnappyArchive(String path)

Initializes a new instance of the [SnappyArchive](../../com.aspose.zip/snappyarchive) class prepared for decompressing.

```

``````

      try (FileInputStream sourceSnappyFile = new FileInputStream("sourceFileName")) {
          try (FileOutputStream extractedFile = new FileOutputStream("extractedFileName")) {
              try (SnappyArchive archive = new SnappyArchive(sourceSnappyFile)) {
                  archive.extract(extractedFile);
              }
          }
      } catch (IOException ex) {
