Recurrence.ExceptionDateNormalizer (Silverpeas Core 6.4 API)

java.lang.Object
- org.silverpeas.core.calendar.Recurrence.ExceptionDateNormalizer

All Implemented Interfaces:

javax.persistence.AttributeConverter<OffsetDateTime,Timestamp>

Enclosing class:

Recurrence
```
public static class Recurrence.ExceptionDateNormalizer
extends Object
implements javax.persistence.AttributeConverter<OffsetDateTime,Timestamp>
```
This converter is dedicated to the Recurrence.exceptionDates collection.
It converts the loaded dates into OffsetDateTime at UTC offset and avoids the collection update during exception dates manipulations. The manipulation of this collection induces database delete/add queries which could produces transaction blocking with some databases. Getting the dates loaded directly as they are attempted into Silverpeas's API avoid to update a date into collection just because it is not same offset, for example.
