Hands-On Design Patterns with C++

Summary

Yet again, we have seen the power of C++ to essentially create a new language out of the existing one; C++ does not have named function arguments, only positional ones. That is part of the core language. And yet, we were able to extend the language and add support for named arguments in a reasonable-looking way, using the method chaining technique. We have also explored the other applications of method chaining beyond the named arguments idiom.

The next chapter introduces the only purely performance-oriented idiom in this book. We have discussed in several chapters the performance cost of memory allocation, and its impact on the implementation of several patterns. The next idiom, local buffer optimization, attacks the problem head-on, ...
