    • isBinary

      public static boolean isBinary​(Reader in)
      Parameters:
      in - the file to check.
      Returns:
      Do the first few bytes of the stream hint at a binary file?

      Any IOException is swallowed internally and the test returns false.

      This method may lead to false negatives if the reader throws an exception because it can't read characters according to the reader's encoding from the underlying stream.

    • isBinary

      public static boolean isBinary​(InputStream in)
      Parameters:
      in - the file to check.
      Returns:
      Do the first few bytes of the stream hint at a binary file?

      Any IOException is swallowed internally and the test returns false.

      This method will try to read bytes from the stream and translate them to characters according to the platform's default encoding. If any bytes can not be translated to characters it will assume the original data must be binary and return true.

    • isBinaryData

      public static boolean isBinaryData​(String name)
      Parameters:
      name - current file name.
      Returns:

    • isNonBinary

      public static boolean isNonBinary​(String name)
      Parameters:
