when passing objects as parameters to constructors...

# getting-started

when passing objects as parameters to constructors, are those objects kept as references in the class being constructed, or are they released once construction is complete? eg

class MyClass(instance: MyObject) {
    val prop = instance.myFun()   
}

would instance be released as soon as construction had completed?

[matt tighe]

additionally, what if prop were lazily instantiated?

Then it would be captured I think.

"released", they're just constructor parameters, not actual fields.

[matt tighe]

@karelpeeters sure, but an instance of MyClass would still need to be passed a reference to instance in order to compute myFun(), no?

[karelpeeters]

Yes, but all that happens in the constructor.
