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 RealHashScanStatistics

---

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 RealHashScanStatistics

---

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 RealHashScanStatistics

---

getNodeOn

public java.lang.String getNodeOn()

If this node is on a database item (like a table or an index), then provide a string that describes the on item.

Overrides:

getNodeOn in class RealHashScanStatistics

---

getNodeName

public java.lang.String getNodeName()

Format for display, a name for this node.

Overrides:

getNodeName in class RealHashScanStatistics

---
