in thread Reading multiple lines?
No qualms at all, I'm trying to get some existing data into a database, and I've got a lot of it. The file structure is a bit odd, and I need to read in N lines of header, then M lines of secondary data, before looping through line by line for a while and then going back to the header structure.
I don't want to read it all into memory because the file is about 160Mb with about 8 million lines. The header is always a fixed number of lines, the secondary data is optional but a fixed number of lines and the bulk of the data is usually somewhere between 100 and 10,000 lines.
I was just surprised that this wasn't as easy / neat to do as I expected. I'm quite pleased with my original map one liner, but nobody has really commented on whether it was really all that bad.
Have fun,
