                             java.lang.Object r)
                      throws EvaluationException

    eval in class BinaryFunction
    
    Throws:
    
    EvaluationException
  - 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'.
