◆ change_combiner()

QueryWildcard* Xapian::Internal::QueryWildcard::change_combiner ( Xapian::Query::op new_op )

inline

Change the combining operator.

If there's only one reference to this object we change in-place and return a pointer to the existing object; otherwise we create and return a new QueryWildcard object.
