XF 1.5 "Parse" attachments on post/reply and edit

i need to parse attachments when they are posted. Its because i want to save additinal info about some types of attachments.
I have found that i can extend forum->createthread, thread->save and thread->reply function/class but they dont fire on edit so i am a bit lost here.

Is there a single hook/extend i could hook into to catch all postings?
