On: C++ Patterns: The Badge

[jcl]

I'm not sure I follow... The motivation for Badge is to have methods on VFS that only Device can call, without exposing VFS's internals to Device. Without Badge, what prevents non-Device functions from calling register_device()?

[taylorconor → jcl]

I guess the inline function would require a Badge and the private member function would not. So an inline constructed but never used Badge is even more likely to be completely optimized away

[dearrifling → taylorconor]

Exactly.
