Summary
This chapter covered the adapter design pattern. The adapter makes things work after they have been implemented. The Pyramid web framework, the Plone CMS, and other Zope-based or related frameworks use the adapter pattern to achieve interface compatibility. In the Implementation section, we saw how to achieve interface conformance using the adapter pattern without modifying the source code of the incompatible model. This is achieved through a generic Adapter class that does the work for us.
Overall, we could use the adapter pattern to make two (or more) incompatible interfaces compatible, which has a lot of usage in software engineering.
In the next chapter, we will cover the decorator pattern.
