#process_statements(target_name, supervisor) ⇒ Object

Central method that starts that processing of the AST. Called by Compiler.

Parameters:

  • target_name (String) —

    Target file name of the extension. The Init_ method is named after this.

  • supervisor (Rubex::CodeSupervisor) —

    Object for holding output code for header and implementation code of each rubex file.
