Creates a ByteArrayInputStream so that it uses buf as its buffer array.

Usage

From source file:Main.java

public static byte[] decompressGzip(byte[] compressed) throws IOException {
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    ByteArrayInputStream bis = new ByteArrayInputStream(compressed);
    GZIPInputStream gis = new GZIPInputStream(bis);
    try {/*from w ww.j  av  a  2  s. co m*/
        byte[] buffer = new byte[READ_BUFFER_SIZE];
        int read = 0;
        while ((read = gis.read(buffer)) != -1) {
            bos.write(buffer, 0, read);
        }
    } finally {
        gis.close();
