unsigned Access: 2 Access - Used by C++ decls for the access specifier.
unsigned FromASTFile: 1 Whether this declaration was loaded from an AST file.
unsigned IdentifierNamespace: 14 IdentifierNamespace - This specifies what IDNS_* namespace this lives in.
unsigned CacheValidAndLinkage: 3 If 0, we have not computed the linkage of this declaration.
StoredDeclsMap * LookupPtr = nullptr Pointer to the data structure used to lookup declarations within this context (or a DependentStoredDeclsMap if this is a dependent context).

Decl * FirstDecl = nullptr FirstDecl - The first declaration stored within this declaration context.
Decl * LastDecl = nullptr LastDecl - The last declaration stored within this declaration context.
DeclLink RedeclLink Points to the next redeclaration in the chain.
ObjCProtocolDecl * First
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;
