| * <b>Purpose:</b> This enumeration provides a means of specifying how a null value in a | |
| * java object should be marshalled to XML. The possible options are:<br> | |
| * <ul> | |
| * <li>XSI_NIL - This means that the element should be written out with an xsi:nil attribute. Example: | |
| * <code><element xsi:nil="true"/></code></li> | |
| * <li>EMPTY_NODE - This indicates that the element should be written out to xml with no contents | |
| * Example: <code><element /></code></li> | |
| * <li>ABSENT_NODE - Absent node means that no element should be written to XML if null is encountered | |
