Code read help request - where are the language specific classes injected? about openapi-generator HOT 1 OPEN

The injection (or loading) of MicronautServerCodegen class is done using Java SPI inteface, more on that topic can be found in the Oracle documentation here https://docs.oracle.com/javase/tutorial/sound/SPI-intro.html or other articles that you can find on the internet. And, the class is loaded by the given generator name, as you assumed in the comment.

Specifically, the class is loaded before DefaultGenerator execute generate from this line Generate.java#L527. If you go through the implementation, the class loading happens at CodegenConfigurator.java#L647 and is executed by CodegenConfigLoader util class. After the class is loaded, an instance is created using reflection and will be used for further generation.
