Overview

Translates EA t_object rows (filtered to classifier types) into the appropriate Ea::Model::Classifier subclass. Uses ObjectClassifierMap for dispatch (OCP — new classifier kinds need no edit here).

def build_one(object)
  klass = classifier_class_for(object)
  args = common_args(object)
  args.merge!(enumeration_args(object)) if klass == Ea::Model::Enumeration
  args.delete(:properties) if klass == Ea::Model::Enumeration
  klass.new(**args)
end

#classifier_class_for(object) ⇒ Object

EA's t_object.Object_Type selects the concrete classifier subclass, but a Class with the "enumeration" stereotype is rendered as an Enumeration (literals compartment, no visibility marker). Promote the model class when the stereotype says so.

#enumeration_stereotype?(object) ⇒ Boolean

Returns:

def enumeration_stereotype?(object)
  stereotype = object.stereotype.to_s
  !stereotype.empty? && stereotype.downcase == "enumeration"
end

#properties_for(object) ⇒ Object

Resolves the classifier's full attribute list. Combines:

1. Own properties from t_attribute
2. Inherited properties from MDG-defined ancestor classes,
 when an mdg_registry is provided AND the classifier's
 applied stereotype maps to an MDG class.

Public so integration tests can drive the merge directly without stubbing the entire build_one pipeline.

When no mdg_registry is wired in, this returns just the own properties — preserving prior behavior.
