We have a `FileFragment` object. In file_csv.cc the name for that object is usually `file`. The `FileFragment` object has the `read_range`. It also has a `FileSource`. `OpenRange` is a method of the `FileSource`. However the FileFragment object doesn't have an open method. `OpenReaderForRangeAsync` and `OpenReaderAsync` are called by the CsvFileFormat, who has access to the FIleFragment. So the CsvFileFormat needs to decide which method to call on the FileSource, by looking at the other field in the FileFragment. Is this clear? Or am I wrong. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
