getChildren
public java.util.Vector<ResultSetStatistics> 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 classRealBasicNoPutResultSetStatistics
- Returns:
- java.util.Vector A vector of objects.
- See Also:
RealBasicNoPutResultSetStatistics.getChildren()

getNodeName
public java.lang.String getNodeName()
Description copied from class:RealBasicNoPutResultSetStatistics
Format for display, a name for this node.- Specified by:

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.
