Hi all, just a quick question: The difference between this:

val Foo = Bar()

and

val Foo
   get() = Bar()

is that when using getter, the evaulation happens every time when accessing

Foo

, right?

Yeah, exactly. In the first line,

Bar()

will be called immediately when the surrounding object is first created, and you're stuck with that particular instance of

Bar

for the rest of the surrounding object's lifetime. In the second line, a new instance of

Bar

is created everytime someone accesses

Foo

, but no permanent reference to any

Bar

will be kept around (at least inside this object).

Thanks for the clarification. Then the latter is exactly what I'll need 🙂

in the second variant your getter has a side effect. so maybe you want to use a real method instead of a getter

It's only a side effect if

Bar()

has a side effect. If

Bar

is just a simple data class, nothing happening there, so I'd say it's not that problematic.

Actually my use case might have side effects, so I think I'll use regular functions instead. Still good to know though, thanks 🙂
