Method Details
-
getStatementExecutionPlanText
Return the statement execution plan as a String.- Parameters:
depth
- Indentation level.- Returns:
- String The statement execution plan as a String.
-
getScanStatisticsText
Return information on the scan nodes from the statement execution plan as a String.- Parameters:
tableName
- if not NULL then print information for this table onlydepth

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
Format for display, a name for this node.- Overrides:

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. -
