That way, the 99% would not pay for it because the default policy would do and (not) store exactly what is done now. An exteded policy could allow tweaking this behavior, for instance by never releasing more than what was explicitly reserved or never automatically releasing at all.
Downside would be that a QByteArray<DefaultPolicy> would not be the same type as a QByteArray<TweakablePolicy>, so assignments and other operations would not just work between them. Might not be worth the trouble. André _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
