Not including anything which depends on the new move library. ------------------------------------------------------------------------ r52746 | danieljames | 2009-05-03 11:12:30 +0100 (Sun, 03 May 2009) | 1 line Merge latest unordered container changes. ------------------------------------------------------------------------ r52747 | danieljames | 2009-05-03 11:15:35 +0100 (Sun, 03 May 2009) | 4 lines Put the C++0x emplace implementations before the non-C++0x versions. I'm going to change the non-C++0x to be macro heavy emulations of the C++0x versions, so this will put the readable version first. ------------------------------------------------------------------------ r52748 | danieljames | 2009-05-03 11:15:44 +0100 (Sun, 03 May 2009) | 1 line Refactor the unordered implementation a tad, to make implementing emplace less painful. ------------------------------------------------------------------------ ........ r52885 | danieljames | 2009-05-10 22:25:09 +0100 (Sun, 10 May 2009) | 1 line Merge emplace support for sandbox - but without move support. ........ r53255 | danieljames | 2009-05-25 20:45:06 +0100 (Mon, 25 May 2009) | 1 line Unordered change log. ........
