Как создать функцию, которая будет иметь один параметр входного массива? [закрыто]

def getRowsByPartitionKeyId(
  id:I, 
  pagingStateOption:Option[PagingState]
): (Option[List[M]], Option[PagingState]) = {

  val resultSet = session.execute(pagingStateOption match {
    case Some(pagingState: PagingState) => 
      whereClause.setFetchSize(1).setPagingState(pagingState)
    case None =>
      whereClause.setFetchSize(1)
  })

  val it = resultSet.iterator();//resultSet is an iterator
  val newPagingState:PagingState = resultSet.getExecutionInfo.getPagingState


  if (it.hasNext) {


    val resultSetAsList:List[Row] = asScalaIterator(it).toList
    val resultSetAsModelList = rowToModel(resultSetAsList.head)


    Tuple2(Some(List(resultSetAsModelList)),Some(pagingState))
  } else {
    Tuple2(None, None)
  }
}
