Annotation Type Mutable

  • @Target({METHOD,FIELD})
    public @interface Mutable
    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.
