Xtext: code generation

In this part we discuss:
– how to “map” Entities Language to Java
– what are multiline template expressions in Xtend
and we implement a transpiler from Entities Language to Java.

Remarks

This part is based on Chapter 5 of L. Bettini’s book Implementing domain-specific languages with Xtext and Xtend.
