How to decompress a gzipped data in a byte array?

Question

I have a class which has a method that is receiving an object as a parameter. This method is invoked via RMI.

public RMIClass extends Serializable {
    pub         


        

Answer 1

Look at those samples, and wherever they're using FileOutputStream, use ByteArrayOutputStream instead. Wherever they're using FileInputStream, use ByteArrayInputStream instead. The rest should be simple.

Answer 2

Why don't you create your own class that extends OutputStream or , whatever is the archive writing to ?

Answer 3

Wrap your byte array with a ByteArrayInputStream and feed it into a GZipInputStream

Answer 4

If you want to write to a ByteBuffer you can do this.

private static void uncompress(final byte[] input, final ByteBuffer output) throws IOException
    {
        final GZIPInputStream inputGzipStream = new GZIPInputStream(new ByteArrayInputStream(input));
        Channels.newChannel(inputGzipStream).read(output);
    }
