- Method Detail
  - addFunction
```
public void addFunction(String id,
                        IFunction f)
```
    Add a function to this function library. The passed function should use the instance of SimuComDefaultRandomNumberGenerator returned by getRandomStream().
    
    Parameters:
    
    id - Name of the function to add. It is the ID in the stoex
    
    f - The function object used during evaluation
  - getRandomStream
```
public de.uka.ipd.sdq.probfunction.math.IRandomGenerator getRandomStream()
```
  - evaluate
```
public Object evaluate(String functionID,
                       ArrayList<Object> parameterValues)
```
    Evaluate the function with the given ID using the given parameters, e.g. f(10,29)
    
    Parameters:
    
    functionID - ID of the function to evaluate
    
    parameterValues - Parameter set to use in evaluation
    
    Returns:
    
    Value of the function evaluated using the given parameters
