Reading private enums that are stored in a multimap as value

I have some trouble accessing and printing the value of an enum class, that is stored inside a multimap, as a value. The error I'm getting is:

error C2228: left of '.getFileType' must have class/struct/union

From what I understand, my pointer is pointing at the enum class and it can't access the getFileType(); function.

Can I do something to access and read the value of the enum (so I can print it out on the console)? My multimap pair must be like the one I did .

Any suggestions are well appreciated, since I really can't work this out with my head.

Thanks for your time!
