FCL-STL from the start has different iterator usage pattern compared to existing containers (say a TSQLQuery). i.e. the common pattern is:
It := SomeContainer.Iterator; while not It.EOF do begin ... It.Next; end; instead, it uses: It := SomeContainer.Iterator; repeat ... until not It.Next; Examining the iterator code, I can see that the latter has at least the following disadvantage: One must add additional guard before executing repeat-until to make sure that the container has at least 1 data. Otherwise, Next in until expression will trigger EAccessViolation. I would like to change the pattern to follow existing one. However, FCL-STL has been available for some time now that changing the pattern will break existing code. How do you think I should proceed on this one? -- View this message in context: http://free-pascal-general.1045716.n5.nabble.com/Changing-iterator-usage-pattern-in-FCL-STL-tp5723038.html Sent from the Free Pascal - General mailing list archive at Nabble.com. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
