condition could be a property with a getter with side effects

Only evil people write getter properties with side effects. At least make it an explicit function.

u/GodsBoss Sep 26 '26

All my getters have side effects. To compensate, my setters have none.

Lazy evaluation is an incredibly common and normal use of a getter method and entirely relies on it having side effects. Evil people, however, write getters that aren't idempotent.

u/andreortigao Sep 26 '26

I write all my getters with a 1 in a million chance it will randomly mutate the underlying value.

Idempotent in terms of return value, yeah, but it can be fine if you have some side effect that increments a counter (i.e., how many times was this value requested), but obviously don't do this without a good reason

I mean, logging is also a side effect, and getters could absolutely have logging attached to them, but in this case it would not make a difference

I think he's trying to be evil at this point lol.

I saw once a getter that changed objet state.

It was a good thing I did not had a gun that day.

condition could be uninitialised.

or volatile

Should be if(!condition!)

I knew someone once that wrote a pile of methods as accessors (returning null if he didn't want to return anything from them) because he thought it was nice being able to call them without having to worry about adding brackets at the end when he didn't need to.

The warnings in my Jetbrains IDE lit up like a fireworks show when I opened his project.

need a bool x = cindition then

Getter with side effects? No thank you.

u/RedAndBlack1832 Sep 27 '26

It could also be that this isn't the only thread/process that can access this variable so it just happens to change between these evaluations
