GzipCompressorOutputStream (Apache Commons Compress 1.8 API)

java.lang.Object
- java.io.OutputStream
- - org.apache.commons.compress.compressors.CompressorOutputStream
  - - org.apache.commons.compress.compressors.gzip.GzipCompressorOutputStream

All Implemented Interfaces:

Closeable, Flushable
```
public class GzipCompressorOutputStream
extends CompressorOutputStream
```
Compressed output stream using the gzip format. This implementation improves over the standard GZIPOutputStream class by allowing the configuration of the compression level and the header metadata (filename, comment, modification time, operating system and extra flags).
