tcp router question about nimdays HOT 3 CLOSED

Thanks for the explanation, now I that made clear!

from nimdays.

I guess the ref object of RootObj is for object inheritance, so object of RootObj is merely means we don't want any inheritance here, is that true? Or there is any other purpose behind scene?

Hi sorry for the confusion

I quickly went through the code

type ForwardOptions = object
  listenAddr*: string
  listenPort*: Port
  toAddr*: string
  toPort*: Port

type Forwarder = object of RootObj
  options*: ForwardOptions


proc newForwarder(opts: ForwardOptions): ref Forwarder =
  result = new(Forwarder)
  result.options = opts

• value types are type MyClass = object .. (allocated on the stack) "can be immutable when initialized with let construct`

• ref types are type MyClass = ref object (allocated on the heap)

• there is initXXX function to create that object on the stack

• there is newXXX function to create the object on the heap

• lots of times you will types like Table[X,Y] and TableRef[X,Y] basically the same but where the object are stored.

RootObj is only used if you want to enable inheritance, and yes It's not used just how I type and autocomplete code. I'll revise and remove what is not needed.
