public String getNodeName()

Implements abstract org.apache.derby.impl.sql.execute.rts.RealNoRowsResultSetStatistics.getNodeName.

Format for display, a name for this node.

getScanStatisticsTextback to summary
public String getScanStatisticsText(String tableName, int depth)

Implements org.apache.derby.iapi.sql.execute.ResultSetStatistics.getScanStatisticsText.

Return information on the scan nodes from the statement execution plan as a String.

Parameters
tableName:String

if not NULL then print information for this table only

depth:int

Indentation level.

Returns:String

String The information on the scan nodes from the statement execution plan as a String.

getStatementExecutionPlanTextback to summary

Implements org.apache.derby.iapi.sql.execute.ResultSetStatistics.getStatementExecutionPlanText.

Return the statement execution plan as a String.

Parameters
depth:int

Indentation level.

Returns:String

String The statement execution plan as a String.

toStringback to summary
public String toString()

Overrides java.lang.Object.toString.
