Package com.evolveum.midpoint.repo.sqale.delta.item

Class ItemDeltaSingleValueProcessor<T>

java.lang.Object

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

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

Type Parameters:

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

All Implemented Interfaces:

ItemDeltaProcessor

Direct Known Subclasses:

EmbeddedContainerDeltaProcessor, ExtensionContainerDeltaProcessor, PolyStringItemDeltaProcessor, RefItemDeltaProcessor, SinglePathItemDeltaProcessor

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

Applies single item delta value to an item. This class implements setRealValues(java.util.Collection<?>) (for multiple values) and requires setValue(T) (for a single value) to be implemented by the subclasses. This hierarchy branch should not need ItemDeltaValueProcessor.addRealValues(java.util.Collection<?>) and ItemDeltaValueProcessor.deleteRealValues(java.util.Collection<?>), so it's not overridden and throws UnsupportedOperationException.

Method Summary

Modifier and Type	Method	Description
protected T	getAnyValue(ItemDelta<?,?> modification)	Often the single real value is necessary, optionally converted using ItemDeltaValueProcessor.convertRealValue(Object) to get expected type.
void	process(ItemDelta<?,?> modification)	Default process implementation, most generic case covering especially multi-values stored in separate rows.
void	setRealValues(Collection<?> values)	Sets the provided real values in the database, implements REPLACE modification.
abstract void	setValue(T value)	Sets the database columns to reflect the provided value (converted if necessary).

Method Detail

process

public void process(ItemDelta<?,?> modification)
             throws RepositoryException,
                    SchemaException

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

getAnyValue

protected T getAnyValue(ItemDelta<?,?> modification)

Often the single real value is necessary, optionally converted using ItemDeltaValueProcessor.convertRealValue(Object) to get expected type. Either method can be overridden or not used at all depending on the complexity of the concrete delta processor.

setValue

public abstract void setValue(T value)
                       throws SchemaException

Sets the database columns to reflect the provided value (converted if necessary).

Throws:

SchemaException

setRealValues

public void setRealValues(Collection<?> values)
                   throws SchemaException

Description copied from class: ItemDeltaValueProcessor

Sets the provided real values in the database, implements REPLACE modification. This may involve setting the value of some columns or delete/insert of sub-entities. This is a general case covering both multi-value and single-value items.

Overrides:

setRealValues in class ItemDeltaValueProcessor<T>

Throws:

SchemaException
