[fedora-java] OT: java question: CharSequence from file

[Christoph Höger]

I tried to use that fragment (after realizing that parallel reading
won't work because of length() function in CharSequence), but this is
_extremely_ slow for larger (>100k) files. Any ideas why?

		StringBuffer inputSequence = new StringBuffer();
		Charset charset = Charset.defaultCharset();
		ByteBuffer byteBuffer = ByteBuffer.allocateDirect(8192);
		
		while (channel.read(byteBuffer) != -1) {
			byteBuffer.flip();
			CharBuffer charBuffer = charset.decode(byteBuffer);
			inputSequence.append(charBuffer);
			byteBuffer.clear();
		}
