- Indentation level.- Returns:
- String The statement execution plan as a String.
-
getScanStatisticsText
public java.lang.String getScanStatisticsText(java.lang.String tableName, int depth)

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.
-
getNodeName
public java.lang.String 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.
