public java.lang.String getStatementExecutionPlanText(int depth)
Return the statement execution plan as a String.

Parameters:
depth - 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()
RealBasicNoPutResultSetStatistics override.

Overrides:
getChildren in class RealBasicNoPutResultSetStatistics
Returns:
java.util.Vector A vector of objects.
