Indexed set library
by Arkadiy Vertleyb 27 Jan '04

27 Jan '04

Hi all, I was just playing with the indexed set library (to provide alternative, set-based, implementation for our RTL tables), and my first impression is that it is very useful. I didn't have any problems in achieving my goal, either with the documentation (which is very clear), or with the library itself. Although I was using the simplest form of indexed_set (I only needed the "compatible predicate" feature missing from std::set), I still think that the idea of having multiple synchronized indexes is very useful (based on my past experience, when I could greatly benefit from such library), and that this library could eventialy become a great addition to Boost. I am wondering what the current state of the library is. I thought the formal review has been requested -- is this correct? Anything new since then? Arkadiy

Sure, but it adds tests, which as we've seen subsequently add delays. It's a feature addition; no two ways about it. -- Dave Abrahams Boost Consulting www.boost-consulting.com

Yeah, but the result is that people would know well in advance when they're scheduled and what library they're scheduled for, and... > I am unsure whether this is not too much pressure to put it on highly > skilled volunteers. ... it would take the pressure off of *you* to find replacement reviewers. But if you're willing to keep that part of the pressure, so much the better for the rest of us. -- Dave Abrahams Boost Consulting www.boost-consulting.com

Another compressed_pair issue
by David Abrahams 26 Jan '04

26 Jan '04

Just for the sake of completeness, it would probably be a good idea to note that the use of compressed_pair wouldn't be transparent on an implementation where a class with virtual functions can be empty. Of course, I doubt any such implementation exists, but it is possible. -- Dave Abrahams Boost Consulting www.boost-consulting.com
