Bang on. If you are running that, it will give you that information. More info can be found in the WordPress codex for the function current_filter()

14,084 Pointsi think i got this , but correct me if i'm wrong . current_filter tells us what filter is being used/run at certain point and makes us being able to add our custom code to that filter .
