getChildren
Description copied from class:RealBasicNoPutResultSetStatistics
Get the objects to be displayed when this tree object is expanded.The objects returned can be of any type, including addtional Inspectables.
- Overrides:

- 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. -
