Class FinalValueDeltaProcessor<T>

java.lang.Object

com.evolveum.midpoint.repo.sqale.delta.ItemDeltaValueProcessor<T>

com.evolveum.midpoint.repo.sqale.delta.item.FinalValueDeltaProcessor<T>

Type Parameters:

T - expected type of the real value for the modification (after optional conversion)

All Implemented Interfaces:

ItemDeltaProcessor

Direct Known Subclasses:

ArrayItemDeltaProcessor, CountItemDeltaProcessor, JsonbPolysItemDeltaProcessor

public abstract class FinalValueDeltaProcessor<T>
extends ItemDeltaValueProcessor<T>

Common delta processor logic for storing based on the final value of the property. When the delta processor is run, the modification has been already applied to the prism object. This is typically used for storing multi-value item in a single column. This may not be efficient when the amount of values is too big, but it has to be really big to be of consequence (my wild guess is 100-1000 can be still OK). Subclasses have to implement ItemDeltaValueProcessor.setRealValues(Collection) and ItemDeltaValueProcessor.delete() methods.

Description copied from class: ItemDeltaValueProcessor

Default process implementation, most generic case covering especially multi-values stored in separate rows. This works when implementations of ItemDeltaValueProcessor.deleteRealValues(java.util.Collection<?>) and ItemDeltaValueProcessor.addRealValues(java.util.Collection<?>) are independent, it's not usable for array update where a single `SET` clause is allowed.

Specified by:

process in interface ItemDeltaProcessor

Overrides:

process in class ItemDeltaValueProcessor<T>

Throws:

RepositoryException

SchemaException
