| * An interface accessor. This is kinda forward thinking. I assume once we |
| * get into full interface support etc. this class will handle much more and |
| * will map directly to an interface schema element from the eclipselink orm |
| * schema. |
| * |
| * Things that should or could be mapped on this interface are: |
| * - alias |
| * - query keys |
| * |
| * Key notes: |
| * - any metadata mapped from XML to this class must be compared in the |
| * equals method. |
| * - any metadata mapped from XML to this class must be handled in the merge |
| * method. (merging is done at the accessor/mapping level) |
| * - any metadata mapped from XML to this class must be initialized in the |
| * initXMLObject method. |
| * - methods should be preserved in alphabetical order. |
