Naming Conventions: What to name a boolean variable?

My vote would be to name it IsLast and change the functionality. If that isn't really an option, I'd leave the name as IsNotLast.

I agree with Code Complete (Use positive boolean variable names), I also believe that rules are made to be broken. The key is to break them only when you absoluately have to. In this case, none of the alternative names are as clear as the name that "breaks" the rule. So this is one of those times where breaking the rule can be okay.

Personally more than anything I would change the logic, or look at the business rules to see if they dictate any potential naming.

Since, the actual condition that toggles the boolean is actually the act of being "last". I would say that switching the logic, and naming it "IsLastItem" or similar would be a more preferred method.

isBeforeTheLastItem

isInFrontOfTheLastItem

isTowardsTheFrontOfTheList

Maybe too wordy but they may help give you ideas.

hasFollowingItems? or hasFollowingXXXXs where XXXX is whatever the item in your list is?
