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

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
Returns:
java.util.Vector A vector of objects.

getNodeName

public java.lang.String getNodeName()
Format for display, a name for this node.

Overrides:
getNodeName in class RealJoinResultSetStatistics

setNames

protected void setNames()

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()

getRSXplainDetails

public java.lang.String getRSXplainDetails()
Specified by:
getRSXplainDetails in interface XPLAINable
Overrides:
getRSXplainDetails in class RealBasicNoPutResultSetStatistics
