  - 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.
