I want to find where I can jump to this

I want to know where this self.transformation will jump to this method, I use bertattack I looked for it in the transformation parent class, but it doesn’t seem to match

I'm assuming you're referring to this portion of the code. The docs indicate the following for Attack.transformation:

transformation (:class:`~textattack.transformations.Transformation`):
            The transformation applied at each step of the attack.

For its transformation variable, it looks like BERTAttack is using WordSwapMaskedLM(method="bert-attack", max_candidates=48) (code here)
