public class AdjustableGZIPOutputStream extends GZIPOutputStream
A customizable extension of GZIPOutputStream that allows users to specify the compression level.

AdjustableGZIPOutputStream enhances the functionality of GZIPOutputStream by providing constructors that let users configure the compression level, enabling control over the trade-off between compression speed and compression ratio.

Key Features

Usage Example


 try (OutputStream fileOut = Files.newOutputStream(Paths.get("compressed.gz"));
      AdjustableGZIPOutputStream gzipOut = new AdjustableGZIPOutputStream(fileOut, Deflater.BEST_COMPRESSION)) {
     gzipOut.write("Example data to compress".getBytes(StandardCharsets.UTF_8));
 }

Additional Notes

  • If the specified compression level is invalid, a IllegalArgumentException will be thrown.
  • The default compression level is Deflater.DEFAULT_COMPRESSION when not specified.
  • The AdjustableGZIPOutputStream inherits all thread-safety properties of GZIPOutputStream.
