WP_Tax_Query::is_first_order_clause │ protected static │ WP 4.1.0

Determines whether a clause is first-order.

A "first-order" clause is one that contains any of the first-order clause keys ('terms', 'taxonomy', 'include_children', 'field', 'operator'). An empty clause also counts as a first-order clause, for backward compatibility. Any clause that doesn't meet this is determined, by process of elimination, to be a higher-order query.
