Method Detail

applySqlSelections	back to summary
public default void applySqlSelections(DomainResultCreationState creationState) Implements org.hibernate.query.sqm.sql.internal.DomainResultProducer.applySqlSelections. Doc from org.hibernate.query.sqm.sql.internal.DomainResultProducer.applySqlSelections. Used when this producer is a selection in a sub-query. The DomainResult is only needed for root query of a SELECT statement. This default impl assumes this producer is a true (Sql)Expression Annotations @Override

combinePredicates	back to summary
public static Predicate combinePredicates(Predicate p1, Predicate p2) Short-cut for `SqlAstTreeHelper#combinePredicates`

createDomainResult	back to summary
public default DomainResult<Boolean> createDomainResult(String resultVariable, DomainResultCreationState creationState) Implements org.hibernate.query.sqm.sql.internal.DomainResultProducer.createDomainResult. Doc from org.hibernate.query.sqm.sql.internal.DomainResultProducer.createDomainResult. Produce the domain query Annotations @Override
