| * Key notes: |
| * - any metadata mapped from XML to this class must be compared in the |
| * equals method. |
| * - when loading from annotations, the constructor accepts the metadata |
| * accessor this metadata was loaded from. Used it to look up any |
| * 'companion' annotation needed for processing. |
| * - methods should be preserved in alphabetical order. |
