If I have some data and want to remove all data that matches the predicate, I would call this predicate my filter condition. If I want to remove all the data that doesn't match the predicate what is the correct way of saying that? Right now I'm using retention condition. Does anyone have a better suggestion?
It's still a filter.
It constists of a logical
NOT followed by your original predicate.
A filter is something that removes some data from your view. Whether that is data that matches a predicate or data that doesn't match a predicate, you are in both cases filtering the data.
