This is called before the query is executed. The handler can add all required selection paths to the given SelectionRegistry.

Specified by:

processSelection in interface SelectionPathHandler

processAdditionalQuery

protected abstract void processAdditionalQuery(AbstractToManySelectionPathHandler.QueryHolder queryHolder,
 List<Path> paths)

extractAllRootPrimaryKeys

protected List<Serializable> extractAllRootPrimaryKeys(List<Object[]> queryResults,
 SelectionRegistry selectionRegistry)

Return all primary keys of the root entity that were found by the original query. These are needed to restrict the additional to-many queries.
