Understanding Type Erasure
Type erasure is often seen as a mysterious, enigmatic programming technique. It is not exclusive to C++ (most tutorials on type erasure use Java for their examples). The goal of this chapter is to lift the shroud of mystery and teach you what type erasure is and how to use it in C++.
The following topics will be covered in this chapter:
- What is type erasure?
- How can we implement type erasure?
- What design and performance considerations must be taken into account when deciding to use type erasure?
