Yes, this is true. But how it is an objection? LSP allows to weaken preconditions, but not to strengthen them - that's exactly what happens. Any method call that worked for base class would also work for derived class, and some other, additional calls, would work too. >> Is it okay to change this? > > I see no reason to do so and I would say -0.5. The reason is that current situation does not match LSP requirements and serves no useful purpose. Especially the second one which literally has the same preconditions but for some weird reason is rejected. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
