Class ExtensionItemSqlMapper<Q extends FlexibleRelationalPathBase<R>,R>

java.lang.Object

com.evolveum.midpoint.repo.sqale.mapping.ExtensionItemSqlMapper<Q,R>

Type Parameters:

Q - entity path owning the mapped item

R - row type with the mapped item

All Implemented Interfaces:

UpdatableItemSqlMapper<Q,R>, ItemSqlMapper<Q,R>

public class ExtensionItemSqlMapper<Q extends FlexibleRelationalPathBase<R>,R>
extends Object
implements UpdatableItemSqlMapper<Q,R>

Extension item mapper that is much lazier than SqaleItemSqlMapper for typical column. Normally the mapper knows how to get from the query/update contextual information to the columns. This mapper only knows the way to the JSONB column and lets extension item filter/delta processors to do the rest of the work based on the context and item information contained in the filter/modification.

Returns primary path for provided entity path - usable for ordering.

Throws:

QueryException

createFilterProcessor

@Nullable
public <T extends ValueFilter<?,
?>>
@Nullable ItemValueFilterProcessor<T> createFilterProcessor(SqlQueryContext<?,?,?> sqlQueryContext)

Description copied from interface: ItemSqlMapper

Creates ItemValueFilterProcessor based on this mapping. Provided SqlQueryContext is used to figure out the query paths when this is executed (as the entity path instance is not yet available when the mapping is configured in a declarative manner). The type of the returned processor is adapted to the client code needs for convenience. Also the type of the provided context is flexible, but with proper mapping it's all safe. [NOTE] This may return null if the subclass supports other type of mapping for this item, but not filtering for queries (e.g. update only item).

createItemDeltaProcessor

public ItemDeltaProcessor createItemDeltaProcessor(SqaleUpdateContext<?,?,?> sqlUpdateContext)
