调研方向

从 traitlets/config/configurable.py 大约第 47 行开始，将父类定义与文档搜索结果进行比较。确定文档是否说明了 self.parent 的语义和预期用途；当行为以及与父 Configurable 实例的关系得到清晰记录时，即视为完成。

描述

Hello, I am making heavy use of self.parent in some code I wrote, but:

  1. searching the docs does not define parent
  2. searching the repo for def parent does not yield any results
  3. There are a number of red herrings in the search to understand what self.parent does and where it is documented because of toy examples in the issues and the docs where we have class Child and Class Parent where the Child class has a slot accessed via self.parent ... this is not the self.parent that is being heavily used in my Traitlets-based applications... but for the life of me, I cannot remember why I started using it and what the semantics are.

Actually I think I found it : it's defined as "The parent Configurable instance of this object." ... ah I think I know the purpose of this... it's to get at the Application class that is the parent of the Configurable class so that you can access slots within the Application... is that correct?
