| 28 | * The Annotation Information Block. |
| 29 | * |
| 30 | * This is the runtime data structure that holds all of the annotation data in |
| 31 | * a form that Retroweaver's runtime can use easily. At weave time, we create |
| 32 | * a public static transient field named [ANNOTATIONS_FIELD] of this type. At |
| 33 | * runtime, we parse the class file, read the annotation data, and populate this |
| 34 | * data structure. |
| 35 | * |
| 36 | * ( Method parameter annotations appear in the same order as method parameters, |
| 37 | * and each parameter gets its own list of Annotations ) |
