Strong typedef for a type T.
Typical usage:
Or:
using StrongTypedef::StrongTypedef;
};
Has all the:
- comparison (see "Operators" below)
- hashing
- streaming operators
- optimizaed logging for LOG_XXX()
If used with container-like type also has common STL functions:
- begin()
- end()
- cbegin()
- cend()
- size()
- empty()
- clear()
- operator[]
Operators: You can customize the operators that are available by passing the third argument of type StrongTypedefOps. See its docs for more info.
