- - ### Constructor Detail

    - #### 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 Detail

    - #### 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

    - #### public void visitClass(ClassNode classNode)

      Prepares invariant-check blocks for the class and adds a synthetic default constructor when needed.

      Parameters:
        `classNode` - the class being visited

    - #### public void visitProperty(PropertyNode node)

      Adds a synthetic setter for invariant-checked properties when no explicit setter is present.

      Parameters:
        `node` - the property being visited
