Method Detail

getStatementExecutionPlanText

public java.lang.String getStatementExecutionPlanText(int depth)

Return 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.

---

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()).

---

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

---

getNodeName

public java.lang.String getNodeName()

Format for display, a name for this node.

Specified by:

getNodeName in class RealBasicNoPutResultSetStatistics

---

initFormatInfo

protected void initFormatInfo(int depth)

Initialize the format info for run time statistics.

---

dumpTimeStats

protected final java.lang.String dumpTimeStats(java.lang.String indent,
                                               java.lang.String subIndent)

Dump out the time information for run time stats.

---

dumpEstimatedCosts

protected final java.lang.String dumpEstimatedCosts(java.lang.String subIndent)

Dump out the estimated cost information

---

getTotalTime

public long getTotalTime()

Return the time for all operations performed by this node, and the children of this node. The times included open, next, and close.

---

getChildrenTime

public long getChildrenTime()

Return the time for all operations performed by the children of this node.

---

getNodeTime

public long getNodeTime()

Return the time for all operations performed by this node, but not the time for the children of this node.

---

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.

---

getEstimatedRowCount

public double getEstimatedRowCount()

Get the estimated row count for the number of rows returned by the associated query or statement.

Specified by:

getEstimatedRowCount in interface ResultSetStatistics
