This member is added by an implicit conversion from SearchForEmptyClauseCommand[V] to
CollectionsHaveToParArray[SearchForEmptyClauseCommand[V], T] performed by method CollectionsHaveToParArray in scala.collection.parallel.
This conversion will take place only if an implicit value of type (SearchForEmptyClauseCommand[V]) ⇒ GenTraversableOnce[T] is in scope.
