- ## Method Details

  - ### matches

    public static boolean matches(byte[] signature, int length)
    Checks if the signature matches ASCII "!<arch>" followed by a single LF control character
    Parameters:
      `signature` - the bytes to check
      `length` - the number of bytes to check
    Returns:
      true, if this stream is an Ar archive stream, false otherwise
