Maybe a comment explaining the guarantees made by this method?

[dmazzoni, 2016/07/28 21:43:16]

I included a lot of documentation in AXObject.h, is there anything in particular
you wanted documentation for in this method? The interface is tricky at first, I
agree, but once you understand it, this implementation is pretty trivial, right?

It was more that I did a bit of a double take at returning here until I realised
you want to guarantee that all of the out params are always something sensible.
But maybe that doesn't need to be stated.
