(1) define a typedef BoolLike to unsigned char, and also define constants TrueLike to 1 and FalseLike to 0.
true implicitly converts to 1, false implicitly to 0, so that last part's mostly unnecessary... Although if we *really* wanted to be able to ignore when we're not using a real bool, we'd need a whole shim class, I think. Otherwise bool foo = 3, bar = 4; assert(foo == bar); suddenly breaks if you try to convert it to BoolLike.
(2) use vector<BoolLike> Nice, contiguous memory, no excess memory usage, and readable.
That's a good idea. We should probably be doing that everywhere we're currently using small vectors of semantically-bool contents. Then it doesn't matter that the question of what's faster is system-dependent; if the answer changes then you just change the typedef accordingly. --- Roy ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-devel mailing list Libmesh-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-devel
