## Intent
|
2017-03-11 12:24:48 +01:00
|
|
|
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.

|
|
* 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
