Summary
This chapter covered the adapter design pattern. We use the adapter pattern for making two (or more) incompatible interfaces compatible. We use adapters every day for interconnecting devices, charging them, and so on.
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 for achieving 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.
In the next chapter, we will cover the decorator pattern.
