A Variation on the Curiously Recurring Template Pattern

摘要

The curiously recurring template pattern splits generic and concrete functionality by delegating to its derived class. Figure 1 depicts this code fragment as UML. For the variation I present here, the term "parametric base class pattern" has been coined. Common to all uses of the pattern that I'm aware of is that a template parameter used to connect generic and concrete functionality is required to fulfill a specific concept. On the other hand, in this article, I do not make any assumptions on the template parameter, and thus, gain flexibility.
