Class SqlDetailFetchMapper<R,I,DQ extends FlexibleRelationalPathBase<DR>,DR>

java.lang.Object

com.evolveum.midpoint.repo.sql.pure.mapping.SqlDetailFetchMapper<R,I,DQ,DR>

Type Parameters:

R - type of master row

I - type of row-PK/detail-FK

DQ - detail Q-type, this will be the base of the select

DR - detail row type (from result)

public class SqlDetailFetchMapper<R,I,DQ extends FlexibleRelationalPathBase<DR>,DR>
extends Object

Mapper/fetcher of many detail records for one master record. Detail fetch/mapper know hows to fetch to-many details related to a master entity.

To load the details for the provided list of data use execute(Supplier, List). To load the details for one master entity use #execute(Supplier, R).

It is easier (and perhaps nicer) to contain all the parametrized types in a single class, that is why execution methods are here.
