function GroupwiseMax::alter_subquery_condition in Views (for Drupal 7) 8.3

Recursive helper to add a namespace to conditions.

Similar to _views_query_tag_alter_condition().

1 call to GroupwiseMax::alter_subquery_condition()

GroupwiseMax::left_query in lib/Drupal/views/Plugin/views/relationship/GroupwiseMax.php

Generate a subquery given the user options, as set in the options. These are passed in rather than picked up from the object because we generate the subquery when the options are saved, rather than when the view is run. This saves considerable time.
