Property setter compile problem

IronHawk · 2016-07-17T16:11:28

Hello! This code isn't compile with an error <<<'test' is not declared>>> at the line if(test != nTest) { class Base { private int m_test; void set_test(int nTest) { m_test = nTest; } int get_test() { return m_test; } } class Derived : Base { private int m_numChanges; void set_test(int nTest) override { if(test != nTest) { Base::set_test(nTest); m_numChanges++; } } } And to allow the code above to be compiled it's necessary to change the row to if(get_test() != nTest) { It seems there's a bug in compiler causing this problem. Thanks!

This looks like intended behavior. After a quick test, it appears that the language allows you to use if (this.test != nTest), which, I think, is less ambiguous than just test anyway, making it clearer that you're using a property accessor but not being explicit about it.

Yes, I checked and if (this.test != nTest) works as expected.

Looks like property access in ObjectiveC and is much more clean than get_test().

Thank you!

I'll look into this behaviour. At the very least to add an explanation about it in the manual. If possible I'll make improvements to the compiler to either allow the access, or give a better error message.
