Detailed Description

ObjCIvarDecl - Represents an ObjC instance variable.

In general, ObjC instance variables are identical to C. The only exception is Objective-C supports C++ style access control. For example:

@interface IvarExample : NSObject { id defaultToProtected; @public: id canBePublic; // same as C++. @protected: id canBeProtected; // same as C++. @package: id canBePackage; // framework visibility (not available in C++). }
