Intent
The purpose of the Converter Pattern is to provide a generic, common way of bidirectional conversion between corresponding types, allowing a clean implementation in which the types do not need to be aware of each other. Moreover, the Converter Pattern introduces bidirectional collection mapping, reducing a boilerplate code to minimum.
Applicability
Use the Converter Pattern in the following situations:
- When you have types that logically correspond which other and you need to convert entities between them
- When you want to provide different ways of types conversions depending on a context
- Whenever you introduce a DTO (Data transfer object), you will probably need to convert it into the domain equivalence
