public Node process(Node node,
                    Node[] children)
             throws ParseException
```
    Pre-process command. Expands and simplifies the child.
    
    Specified by:
    
    process in interface CommandVisitorI
    
    Parameters:
    
    node - top node of the tree
    
    children - the children of the node after they have been preprocessed.
    
    Returns:
    
    top node of the results.
    
    Throws:
    
    ParseException
  - init
```
public void init(Jep jep)
```
    Description copied from interface: JepComponent
    
    Initialize the component. This methods is called whenever a component is added to Jep. Hence it allows components to keep track of the other components they may rely on.
    
    Specified by:
    
    init in interface JepComponent
    
    Parameters:
    
    jep - the current Jep instance
  - getLightWeightInstance
```
public JepComponent getLightWeightInstance()
```
    Description copied from interface: JepComponent
    
    Gets a light-weight instance suitable for using in multiple threads.
    
    Specified by:
    
    getLightWeightInstance in interface JepComponent
    
    Returns:
    
    either an new instance, null or 'this'.
