This is a “single action visitor”, meaning it is passed the whole data vector in one call and you must use the single_act_visit() interface. This functor class finds the Kth element in the given column in linear time.

T: Column data type I: Index type. A: Memory alignment boundary for vectors. Default is system default alignment |
