Detailed Description
Represents an Objective-C protocol declaration.
Objective-C protocols declare a pure abstract type (i.e., no instance variables are permitted). Protocols originally drew inspiration from C++ pure virtual functions (a C++ feature with nice semantics and lousy syntax:-). Here is an example:
\@protocol NSDraggingInfo <refproto1, refproto2>
- (NSWindow *)draggingDestinationWindow;
- (NSImage *)draggedImage;
\@end
This says that NSDraggingInfo requires two methods and requires everything that the two "referenced protocols" 'refproto1' and 'refproto2' require as well.
\@interface ImplementsNSDraggingInfo : NSObject \<NSDraggingInfo>
\@end
ObjC protocols inspired Java interfaces. Unlike Java, ObjC classes and protocols are in distinct namespaces. For example, Cocoa defines both an NSObject protocol and class (which isn't allowed in Java). As a result, protocols are referenced using angle brackets as follows:
id <NSDraggingInfo> anyObjectThatImplementsNSDraggingInfo;
