 ResultSetStatistics sourceResultSetStatistics)

Method Details

getStatementExecutionPlanText

public 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 String getScanStatisticsText(String tableName,
 int depth)

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

Parameters:

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

depth - Indentation level.

Returns:

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

toString

public String toString()

Overrides:

toString in class Object

getNodeName

public String getNodeName()

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

Specified by:

getNodeName in class RealNoRowsResultSetStatistics

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 String getRSXplainType()

getResultSetDescriptor

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

Specified by:

getResultSetDescriptor in interface XPLAINable

Overrides:

getResultSetDescriptor in class RealNoRowsResultSetStatistics
