Questions tagged [convenience-methods]

Convenience methods are shorthand abstractions which invoke another method by implicitly passing in default argument(s) for a common use case

Convenience methods are intended to encapsulate the verbosity of an existing API into a single expression by aliasing a method call or set of method calls with default arguments to a new method which represents a specific operation.

I recently decided to take a look at 2D graphics with C++, using MinGW on Windows 7. Since I was only going to need 2D graphics any library would be viable more or less (OpenGL, SDL, etc..). I decided to take a quick look at a few and check how easy…

Class design: allow a class to be used both as an object and also supply public static methods

I have a silly, little class "FileSystemSize" which can be used both as an object and also via public, static methods. The output is similar, but not identical in each case. The class was intially static, but I added the possibility to initialize it…
