CHAPTER 4
Overload Resolution
This chapter presents TMP techniques based on overload resolution.
The common underlying schema is as follows:
- You want to test if type T satisfies a condition.
- You write several static functions with the same name, say test, and pass them a dummy argument that “carries” type T (in other words, an argument that allows deduction of T, such as T*).
- The compiler selects the best candidate, according to C++ language rules.
- You deduce which function was used, either using the return type or indirectly from a property of this type, and eventually make a decision.
