RefTableTargetResolver (midPoint Aggregate JavaDoc)

java.lang.Object
- com.evolveum.midpoint.repo.sqale.mapping.RefTableTargetResolver<Q,R,TQ,TR>

Type Parameters:

Q - type of reference entity path (where the mapping is)

R - row type for RefTableTargetResolver

TQ - type of target entity path, that is referenced object

TR - row type related to the target entity path RefTableTargetResolver

All Implemented Interfaces:

ItemRelationResolver<Q,R,TQ,TR>
```
public class RefTableTargetResolver<Q extends QReference<R,?>,R extends MReference,TQ extends QObject<TR>,TR extends MObject>
extends Object
implements ItemRelationResolver<Q,R,TQ,TR>
```
Resolver that knows how to traverse from reference table to the reference target. The resolver uses mapping lazily via supplier to avoid call cycles during mapping initialization. Ideal mapping type provided by the supplier is to be found in the schema inside `` element for the reference, using more generic type means Postgres has to search through more sub-tables than necessary and also doesn't provide the right implicit type for further conditions on the target.

    Description copied from interface: ItemRelationResolver
    
    Resolves a query context to ItemRelationResolver.ResolutionResult with new context and mapping. The information about the resolved item is captured in the instance resolver already in a manner that is specific for various types of resolution (subquery or nested mapping).
