| <div class="block">A Mutable annotation can be used on a @Basic mapping. |
| It can be used on complex field types to indicate that the value itself can be changed or not changed (instead of being replaced). |
| Most basic types are not mutable, i.e. int, long, float, double, String, BigDecimal. |
| Date or Calendar types are assumed not to be mutable by default, if it is desired to call |
| the set methods on the Date or Calendar, then the mapping must be set to be @Mutable. |
| For Date and Calendar types the global persistence property "eclipselink.temporal.mutable" can also be set to "true". |
| For serialized types, by default they are assumed to be mutable, if they are not mutable this annoation can be set to false. |
| Mutable basic mappings affect the overhead of change tracking, attribute change tracking can only be weaved with non-mutable mappings.</div> |
