org.apache.commons.compress.compressors.CompressorStreamFactory

Factory to create Compressor[In|Out]putStreams from names. To add other implementations you should extend CompressorStreamFactory and override the appropriate methods (and call their implementation from super of course).

Example (Compressing a file):

 final OutputStream out = new FileOutputStream(output);  CompressorOutputStream cos =  new CompressorStreamFactory().createCompressorOutputStream(CompressorStreamFactory.BZIP2, out); IOUtils.copy(new FileInputStream(input), cos); cos.close();

Example (Decompressing a file):

 final InputStream is = new FileInputStream(input);  CompressorInputStream in =  new CompressorStreamFactory().createCompressorInputStream(CompressorStreamFactory.BZIP2, is); IOUtils.copy(in, new FileOutputStream(output)); in.close();

@Immutable

    private File uncompress(File gz) throws IOException, CompressorException {
        final File output = new File(gz.getParent(), FilenameUtils.getBaseName(gz.getName()));
        output.delete();


        final InputStream is = new FileInputStream(gz);
        final CompressorInputStream in = new CompressorStreamFactory().createCompressorInputStream("gz", is);
        IOUtils.copy(in, new FileOutputStream(output));
        in.close();


        return output;
    }
