Instance variable access from functions


  • Subject: Instance variable access from functions

Is the non-protected access of instance variables from functions defined inside of @implementations documented anywhere? I'm wondering if this some secret thing that I shouldn't use, or something that's actually pretty common used?




@interface Foo : NSObject
{
	int special;
}

- (void)print;

@end




@implementation Foo

static inline void dotheprint(Foo * self)
{
NSLog(@"%d", self->special); // If defined outside @imp it'd give a compiler error
}


- (id)init;
{
	[super init];
	special = 5;
	return self;
}

- (void)print;
{
	dotheprint(self);
}

@end
