Thread: How do I add a window to my program?

Not obvious though, since such additional functionality can often be added by extending the interface with non-member non-friend functions with no or negligible loss of efficiency. In fact, I recall that Sutter used std::basic_string as an example of a string class with too bloated a core interface such that it is monolithic.

My concern is less with efficiency, and more with productivity and convenience.

O_o

Properly written non-member non-friend polymorphic interfaces increase productivity.

Given that we have three string utilities--`ElkvisString', `laserlightString', and `PhantomString'--in the same application, for whatever reasons, we can create a `ToUpper' interface for each. Client code, thus the developer, doesn't need to remember to use `std::transform' with `laserlightString' or `ElkvisString::toupper' with `ElkvisString' or how to invoke locale specific `convertCase' with `PhantomString'; the developer can just use, creating if necessary, the same `ToUpper' interface.

Not needing to know how to spell "convert all characters to upper case" or "trim leading whitespace" for a given string is a blessing.

The `PhantomString' is best string.

I suggest reading:

• Designing Simple Interfaces, from an interview of Bjarne Stroustrup
• How Non-Member Functions Improve Encapsulation by Scott Meyers
• GotW #84: Monoliths "Unstrung", the article by Herb Sutter that I alluded to earlier

Code:

   myPhantomString.AppendFunnyFace( FF_RIGHT_WINK );

Output: Greatest invention since sliced bread! ^.0
