Method Detail

getStatementExecutionPlanText

public java.lang.String getStatementExecutionPlanText(int depth)

Return the statement execution plan as a String.

Specified by:

getStatementExecutionPlanText in interface ResultSetStatistics

Overrides:

getStatementExecutionPlanText in class RealScalarAggregateStatistics

---

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.

Specified by:

getScanStatisticsText in interface ResultSetStatistics

Overrides:

getScanStatisticsText in class RealScalarAggregateStatistics

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:

toString in class RealScalarAggregateStatistics

---

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 RealScalarAggregateStatistics

---

getNodeName

public java.lang.String getNodeName()

Format for display, a name for this node.

Overrides:

getNodeName in class RealScalarAggregateStatistics

---
