Class Method Details

.generate_obj_methods(fn_name, arch_dir, obj_class)

This method returns an undefined value.

These instance methods are create when this Architecture class is first loaded. This is a Ruby “class” method and so self is the entire Architecture class, not an instance it. However, this class method creates normal instance methods and when they are called self is an instance of the Architecture class.

Parameters:

  • fn_name (String)
  • arch_dir (String)
  • obj_class (T.class_of(DatabaseObject))
