in classRealBasicNoPutResultSetStatistics
- Returns:
- java.util.Vector A vector of objects.
-

accept
Description copied from interface:XPLAINable
This method gets called to let a visitor visit this XPLAINable object. The general contract is to implement pre-order, depth-first traversal to produce a predictable traversal behaviour. -
