  - ### createPropInit

    public abstract Statement createPropInit(AbstractASTTransformation xform, AnnotationNode anno, ClassNode cNode, PropertyNode pNode, Parameter namedArgMap)
    Create a statement that will initialize the property including any defensive copying. Null if no statement should be added.
    Parameters:
      `xform` - the transform being processed
      `anno` - the '@ImmutableBase' annotation node

  - ### createPropGetter

    public Statement createPropGetter(PropertyNode pNode)
    Create the getter block used when reading the property including any defensive copying.
    Parameters:
      `pNode` - the property node

  - ### createPropSetter

    public Statement createPropSetter(PropertyNode pNode)
    Create the setter block used when setting the property. Can be null for read-only properties.
    Parameters:
      `pNode` - the property node

  - ### isValidAttribute

    protected boolean isValidAttribute(AbstractASTTransformation xform, AnnotationNode anno, String memberName)

  - ### createPropertyHandler
