Marco Leise <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #4 from Marco Leise <[email protected]> 2012-08-15 06:22:24 PDT --- I think Delphi has the most convenient implementation of sets. type TWorkDay = (Monday, Tuesday, Wednesday, Thursday, Friday) ; TDaySet = set of TWorkDay; var days : TDaySet; begin days := [Monday, Friday]; days := days + [Tuesday, Thursday] - [Friday]; if Wednesday IN days then ShowMessage('I love Wednesday!') ; It also uses the 2^n binary notation internally. Any proposed solution should add safety as well as the basic set operators. As long as it is still easier to write "set &= ~flag" to remove a flag from a set, it failed its mission. It would be even better if a set type would be allowed in bindings to C code or painlessly converted to it's integer representation with "set.val" or similar. :) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
