| * build aggregate data structures such as search engine indices or glossaries. |

| * The CPM will also call each CAS Consumer's {@link #batchProcessComplete(ProcessTrace)} method at |
| * the end of each batch and their {@link #collectionProcessComplete(ProcessTrace)} method called at |
| * the end of the collection. |
