Overview

Transforms EA ObjectConstraint to UML Constraint

This transformer converts Enterprise Architect constraint definitions (typically OCL constraints) to standard UML Constraint objects.

Examples:

Transform a constraint

ea_constraint = Models::EaObjectConstraint.new(
  constraint_id: 1,
  object_id: 4,
  constraint: "count(self.legalConstraints) >= 1",
  constraint_type: "Invariant",
  weight: 0.0,
  status: "Approved"
)
transformer = ConstraintTransformer.new(database)
uml_constraint = transformer.transform(ea_constraint)
