  - ### Method Detail

    - #### public Statement createPropGetter(PropertyNode pNode)

      Create the getter block used when reading the property including any defensive copying.

      Parameters:
        `pNode` - the property node

    - #### 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
        `cNode` - the classnode containing the property
        `pNode` - the property node to initialize
        `namedArgMap` - an "args" Map if the property value should come from a named arg map or null if not

    - #### 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

    - #### public static PropertyHandler createPropertyHandler(AbstractASTTransformation xform, GroovyClassLoader loader, ClassNode cNode)

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

    - #### public abstract boolean validateAttributes(AbstractASTTransformation xform, AnnotationNode anno)

    - #### public boolean validateProperties(AbstractASTTransformation xform, BlockStatement body, ClassNode cNode, List<PropertyNode> props)
