  - ### validateAttributes

    public boolean validateAttributes(AbstractASTTransformation xform, AnnotationNode anno)
    Validates annotation attributes supported by this handler.
    Specified by:
      `validateAttributes` in class `PropertyHandler`
    Parameters:
      `xform` - the active transform
      `anno` - the property options annotation
    Returns:
      `true` if validation succeeds

  - ### validateProperties

    public boolean validateProperties(AbstractASTTransformation xform, BlockStatement body, ClassNode cNode, List<PropertyNode> props)
    Validates the properties selected for processing.
    Overrides:
      `validateProperties` in class `PropertyHandler`
    Parameters:
      `xform` - the active transform
      `body` - the statement block being generated
      `cNode` - the owning class
      `props` - the candidate properties
    Returns:
      `true` if validation succeeds

  - ### createPropInit

    public Statement createPropInit(AbstractASTTransformation xform, AnnotationNode anno, ClassNode cNode, PropertyNode pNode, Parameter namedArgsMap)
    Create a statement that will initialize the property including any defensive copying. Null if no statement should be added.
    Specified by:
      `createPropInit` in class `PropertyHandler`
    Parameters:
      `xform` - the transform being processed
      `anno` - the '@ImmutableBase' annotation node
      `cNode` - the classnode containing the property
      `pNode` - the property node to initialize
      `namedArgsMap` - an "args" Map if the property value should come from a named arg map or null if not
