Codegen

An howto for codegen.

Preliminary

Codegen is able to handle model generation for different kind of models:

• module

• package

• class/interface types

• dataobject

Any class/interface or dataobject always belons to a package and most importantly to a module

Class generation steps

• generate the target lang class files with an empty class and make them compile: ReadStream

• generate imports, so each target class is able to import the classes it depends on: TimeoutStream imports ReadStream

• distinguish between concrete and abstract types: ReadStream is abstract and TimeoutStream is concrete

• add generic support if any on class model declaration: ReadStream<T>

• add inheritance support

  • generics: TimeoutStream extends ReadStream<Long>, etc…​

  • super concrete type and super abstract types: AsyncFile extends ReadStream<Buffer> and WriteStream<Buffer>
