getChildren
public java.util.Vector 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:
getChildren
in class RealBasicNoPutResultSetStatistics
- Returns:
- java.util.Vector A vector of objects.
- See Also:

RealBasicNoPutResultSetStatistics.getNodeName()
accept
public void accept(XPLAINVisitor visitor)
- 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.
