  15 # Compile Nit code to Java code
  16 #
  17 # 3 runtime structures are used to represent Nit instance in Java generated code:
  18 # * `RTClass` to represent a class, it's super-type table and its VFT
  19 # * `RTMethod` to reprensent a compiled method definition
  20 # * `RTVal` to reprensent a Nit instance, the null value or a native value
  21 #
  22 # More details are given in the documentation of these 3 classes.

  24 # TODO Factorize with `abstract_compiler`
