- ## Constructor Details

  - ### DynamicSetterInjectionVisitor

    public DynamicSetterInjectionVisitor(SourceUnit sourceUnit, ReaderSource source)
    Creates a visitor that injects synthetic setters and constructors needed for invariant checks.
    Parameters:
      `sourceUnit` - the source unit currently being transformed
      `source` - the reader source backing the source unit

- ## Method Details

  - ### createSetterBlock

    protected Statement createSetterBlock(ClassNode classNode, FieldNode field, Parameter parameter)
    Creates the body of a synthetic setter that wraps the assignment with invariant checks.
    Parameters:
      `classNode` - the declaring class
      `field` - the field being written
      `parameter` - the synthetic setter parameter
    Returns:
      the generated setter body

  - ### visitProperty

    public void visitProperty(PropertyNode node)
    Adds a synthetic setter for invariant-checked properties when no explicit setter is present.
    Specified by:
      `visitProperty` in interface `GroovyClassVisitor`
    Overrides:
      `visitProperty` in class `ClassCodeVisitorSupport`
    Parameters:
      `node` - the property being visited

  - ### visitClass

    public void visitClass(ClassNode classNode)
    Prepares invariant-check blocks for the class and adds a synthetic default constructor when needed.
    Specified by:
      `visitClass` in interface `GroovyClassVisitor`
    Overrides:
      `visitClass` in class `ClassCodeVisitorSupport`
    Parameters:
      `classNode` - the class being visited
