    Parameters:
    
    depth - Indentation level.
    
    tableName - if not NULL then print information for this table only
    
    Returns:

    toString in class java.lang.Object
  - getNodeOn
```
public java.lang.String getNodeOn()

  - 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.
