Writes remaining compressed data to the output stream and closes the underlying stream.

Usage

From source file:nl.nn.adapterframework.util.Misc.java

public static byte[] gzip(byte[] input) throws IOException {

    // Create an expandable byte array to hold the compressed data.
    // You cannot use an array that's the same size as the orginal because
    // there is no guarantee that the compressed data will be smaller than
    // the uncompressed data.
    ByteArrayOutputStream bos = new ByteArrayOutputStream(input.length);
    GZIPOutputStream gz = new GZIPOutputStream(bos);
    gz.write(input);//from w  w  w .  ja  v a2s  .c om
    gz.close();
    bos.close();

    // Get the compressed data
    return bos.toByteArray();
