Using an enumeration as a template parameter

Question

I would like to use a template class to provide some common functionality to some child classes that are very similar. The only variation is the enumeration that each uses.

Answer 1

The syntax goes for value arguments like it is for typename arguments. Basically, you just replace typename with the name of your enum:

enum Foo { Bar, Frob };

template  struct Boom {};  // primary template
template <> struct Boom {};  // specialization of whole class

...

template <> void Boom::somefun() {}  // specialization of single member
