Method Details

getSelection

protected abstract javax.persistence.criteria.Selection<?> getSelection()

createMapperFunction

protected abstract Function<List<Object[]>,List<RT>> createMapperFunction()

getResultList

public final List<RT> getResultList()

Specified by:

getResultList in interface CriteriaQueryWrapper<RT>

distinct

public CriteriaQueryWrapper<RT> distinct(boolean value)

Specified by:

distinct in interface CriteriaQueryWrapper<RT>

uniqueResultOptional

public final Optional<RT> uniqueResultOptional()

Specified by:

uniqueResultOptional in interface CriteriaQueryWrapper<RT>

uniqueResultOptional

public final Optional<RT> uniqueResultOptional(javax.persistence.LockModeType lockMode)

Specified by:

uniqueResultOptional in interface CriteriaQueryWrapper<RT>

firstResultOptional

public final Optional<RT> firstResultOptional()

Specified by:

firstResultOptional in interface CriteriaQueryWrapper<RT>

expandSelection

protected javax.persistence.criteria.Selection<Object[]> expandSelection(List<javax.persistence.criteria.Order> order)

If we use 'DISTINCT', selection needs to include all columns used in 'ORDER BY'. If the order by column is not part of the selection it needs to be explicitly added to the selection.

isPartOfSelection

protected abstract boolean isPartOfSelection(javax.persistence.criteria.Path<?> path)

determineOrderBy

protected List<javax.persistence.criteria.Order> determineOrderBy()

createExpandedSelection

protected javax.persistence.criteria.Selection<Object[]> createExpandedSelection(javax.persistence.criteria.Selection<?> originalSelection,
 List<javax.persistence.criteria.Selection<?>> additionalSelectionPaths)
