Confused by Syntax

I was looking at a sample for NSToolbar. I saw this method:

- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar itemForItemIdentifier:(NSString *)itemIdentifier willBeInsertedIntoToolbar:(BOOL)flag

What is going on here? The method name is itemForItemIdentifier, OK fine. We have an itemIdentifier param which is an NSString*. We have a willBeInsertedIntoToolbar param which is a BOOL. OK that's all well.

But then what does this "- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar" mean?

Does it mean we are returning an NSToolbarItem* ? If so, then what does "toolbar:(NSToolbar *)toolbar" mean? I don't get it. It almost looks like we are returning two values at once, but that wouldn't make sense either because both items are named as "toolbar", identical naming!

I'm totally floored by this one.
