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 RealDeleteResultSetStatistics

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.

Specified by:

getScanStatisticsText in interface ResultSetStatistics

Overrides:

getScanStatisticsText in class RealDeleteResultSetStatistics

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.

getNodeName

public java.lang.String getNodeName()

Format for display, a name for this node.

Overrides:

getNodeName in class RealDeleteResultSetStatistics

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.

Specified by:

accept in interface XPLAINable

Overrides:

accept in class RealDeleteResultSetStatistics

getRSXplainDetails

public java.lang.String getRSXplainDetails()

Specified by:

getRSXplainDetails in interface XPLAINable

Overrides:

getRSXplainDetails in class RealNoRowsResultSetStatistics
