Overview

Represents a constraint type definition from t_constrainttypes table

This table provides reference data for constraint types used in OCL constraints. These are NOT instances of constraints, but the type definitions themselves (Invariant, Pre-condition, Post-condition, Process).

Examples:

constraint_type = EaConstraintType.new
constraint_type.constraint #=> "Invariant"
constraint_type.description #=> "A state the object must always..."
