- Indentation level.
- Returns:
- String The statement execution plan as a String.
getScanStatisticsText
public java.lang.String getScanStatisticsText(java.lang.String tableName,
int depth)
- Return information on the scan nodes from the statement execution
plan as a String.
- Parameters:

toString
public java.lang.String toString()
- Overrides:
toString
in class java.lang.Object
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.
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.

public java.lang.String getRSXplainType()
getRSXplainDetails
public java.lang.String getRSXplainDetails()
- Specified by:
getRSXplainDetails
in interface XPLAINable
- Overrides:
