the class BinaryDictionaryWriter method writeDictionary.

protected void writeDictionary(String filename) throws IOException {
    new File(filename).getParentFile().mkdirs();
    final FileOutputStream os = new FileOutputStream(filename);
    try {
        final DataOutput out = new OutputStreamDataOutput(os);
        CodecUtil.writeHeader(out, BinaryDictionary.DICT_HEADER, BinaryDictionary.VERSION);
        out.writeVInt(buffer.position());
        final WritableByteChannel channel = Channels.newChannel(os);
        // Write Buffer
        // set position to 0, set limit to current position
        buffer.flip();
        channel.write(buffer);
        assert buffer.remaining() == 0L;
    } finally {
        os.close();
