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 executio 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.
