Templated helper to make a type-safe 'typedef' representing a single POD value.
A normal 'typedef' is not distinct from its base type and will be treated as identical in many contexts. This class provides a distinct type that can still be assign from and compared to values of its base type.
Example usage:
using MyType = StrongType::Typedef<int, struct MyTypeTag, StrongType::Explicit, StrongType::Compare, StrongType::Integer>;
TBaseType | Type of the derived class (i.e. the concrete usage of this class). |
TTag | An unique struct to keep types of the same TBaseType distinct. |
TProperties | A list of mixins to add to the class. |
