| /** |
| * This is an annotation on a class, currently just {@link ASTTransformation}. |
| * This provides information about how and when to apply the transformation, |
| * such as what phase it should be applied in. |
| * |
| * The allowed phase is a function of how the transformation is introduced |
| * into the compile process. If the transform is automatically added via a |
| * marker annotation only the SEMANTIC_ANALYSIS and latter phases are legal |
| * for the phase(). This is because the annotations are not inspected until |
| * after the classes are all resolved. |
| * |
| * Also, only annotation types present during the SEMANTIC_ANALYSIS phase |
| * will be handled. Transformations adding other annotations that are |
| * transformable will have those new annotations only considered in |
| * latter phases, and only if the type was present in the source unit |
| * during SEMANTIC_ANALYSIS. |
