It has operator<< and operator>> so I guess you could load it from a file. It’s an interesting point though, if you have a fixed set of data then you could use a perfect hash and a perfect number of buckets. There’s undoubtedly some other library which can do that. I googled and found stuff like https://news.ycombinator.com/item?id=10745194 and http://stevehanov.ca/blog/index.php?id=119 which have more links to things like cmph and gperf. But for tokenizing, maybe just use lex/flex? _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
