        1.1

    - #### count

          protected void count(long read)

      Increments the counter of already read bytes. Doesn't increment if the EOF has been hit (read == -1)
      Parameters:
        `read` - the number of bytes read

    - #### pushedBackBytes

          protected void pushedBackBytes(long pushedBack)

      Decrements the counter of already read bytes.
      Parameters:
        `pushedBack` - the number of bytes pushed back.
      Since:
        1.7

    - #### getCount

          @Deprecated
          public int getCount()

      Deprecated. this method may yield wrong results for large archives, use #getBytesRead instead
      Returns the current number of bytes read from this stream.
      Returns:
        the number of read bytes

    - #### getBytesRead

          public long getBytesRead()

      Returns the current number of bytes read from this stream.
      Returns:
        the number of read bytes
