RealUpdateResultSetStatistics

public RealUpdateResultSetStatistics(int rowCount,
                                     boolean deferred,
                                     int indexesUpdated,

Method Detail

getStatementExecutionPlanText

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:

depth - Indentation level.

tableName - if not NULL then print information for this table only

Returns:

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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getNodeName

public java.lang.String getNodeName()

Format for display, a name for this node. Since this is a SQL operator name, it does not need to be internationalized.

accept

public void accept(XPLAINVisitor visitor)

Description copied from interface: XPLAINable

This method gets called to let a visitor visit this XPLAINable object. The general contract is to implement pre-order, depth-first traversal to produce a predictable traversal behaviour.

getRSXplainType

public java.lang.String getRSXplainType()

getResultSetDescriptor

public java.lang.Object getResultSetDescriptor(java.lang.Object rsID,
                                               java.lang.Object parentID,
                                               java.lang.Object scanID,
                                               java.lang.Object sortID,
                                               java.lang.Object stmtID,
                                               java.lang.Object timingID)

Specified by:

getResultSetDescriptor in interface XPLAINable

getChildren

public java.util.Vector<ResultSetStatistics> getChildren()

Get the objects to be displayed when this tree object is expanded.

The objects returned can be of any type, including addtional Inspectables.

Returns:

java.util.Vector A vector of objects.

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

Returns:

The estimated number of rows returned by the associated query or statement.
