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<ResultSetStatistics> 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. Since this is a SQL operator name, it does not need to be internationalized.
  
  Specified by:
  
  getNodeName in class RealBasicNoPutResultSetStatistics
- 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
- getResultSetDescriptor
```
public java.lang.Object getResultSetDescriptor(java.lang.Object rsID,
                                               java.lang.Object parentID,
