Here is the thing. I have a class that functions as a log writer. I would like to create an instance of this class that can be seen by every other class in my program.
How can I do this?

2Some people might deny it but that would be a singleton. – user7860670 May 31 '18 at 20:21

1@VTT not saying you are not right, but globals/singletons are just *so much* pain waiting to happen - it makes me sad. – Jesper Juhl May 31 '18 at 20:32

@JesperJuhl I kindly decline singleton battle challenge by stating that implementing a singleton pattern is just a rational way of avoiding overhead of passing / storing references to a commonly used object everywhere. – user7860670 May 31 '18 at 21:02

@VTT let's leave it at that. – Jesper Juhl May 31 '18 at 21:05

@VTT: singleton offers global access, but also only one instance of the class. OP doesn't state that other instance should be avoided. – Jarod42 Jun 01 '18 at 08:21
