when i run this.iterator() which calls invoke(Int)...

# stdlib

when i run this.iterator() which calls invoke(Int) should i assume origin is the vtable for IDataframe::invoke(Int) ?
do i need to manually delegate each method i wish to expose if I iwsh to use specialized methods I write in the delegator ?

class FrameGrouper(
    private val origin: IDataFrame,
    vararg val gby: Int
) :  IDataFrame  by origin  {
    override fun invoke(row: Int) =...}

Can you show some more complete code? Why would this.iterator() call invoke? And where do vtables come it?

[jimn]

i am debugging it now. "by origin" is a total headache.

That's a lot of code...

[jimn]

yeah the delegation is really causing me to backtrack every method in the origin class and make a delegator method even if its the same code

[jimn]

it's better if i make the delegation manual here since they are doing different things under the hood

@jimn btw format code by wrapping with ` or ```
