What does < > mean / represent in a class interface?

Question

I am sure I have read this somewhere, Can anyone tell me what the < > represent in the following interface?

@interface GameFinder : NSObject 

        

Answer 1

< > represent a protocol (or list of protocols) to which a class conforms. An Objective-C protocol is like an interface in Java: it's a list of methods that the conforming class must implement.
