public static int[] getIntArray(ByteBuffer data, int offset, int length) {
    if (length == 0) {
        return new int[0];
    }/*  w w  w.j  a va 2s  .  c  om*/
    data.position(offset);
    int[] intArray = new int[length / 2];
    int index = 0;
    while (index < intArray.length) {
        intArray[index++] = data.getShort();
    }
    return intArray;
