Reading time min The Adapter design pattern is a design pattern that is very simple to implement and use yet widely used. In this entry I will show you what the adapter can be used for and present an example implementation of the Adapter in TypeScript. I have made every effort to ensure that the examples are understandable and easy to translate into other commonly used object oriented languages. This post is another entry in the series about design patterns. If you want to explore other design patterns or learn what patterns are be sure to check out my post about design patterns.
Application When talking about the Adapter you can associate it with adapters for electrical sockets or popular ports in electronic devices. This association is absolutely correct. An adapter Phone Number List in software engineering as in everyday life is used to connect two incompatible interfaces together. The simplest implementation of the Adapter pattern is shown in the UML diagram below. Adapter pattern UML diagram.
The first class in the diagram above is the client i.e. the adapter user. Its role is only to call the method Much more interesting classes are Let's assume tis a class used in a huge system and the number of its occurrences is in the hundreds. Additionally the class from outside the organization for example from an external dependency and its structure cannot be changed. The parameters that the method takes three string values and an optional parameter a default value false. After some time it was decided that the parameteto be set to true throughout the system and that it would be more convenient to pass the values as an object instead of a list of parameters.
