  - configure
```
public void configure(Parameterization config)
```
    Description copied from interface: Parameterizer
    
    Configure the class.
    Note: the status is collected by the parameterization object, so that multiple errors may arise and be reported in one run.
    
    Specified by:
    
    configure in interface Parameterizer
    
    Parameters:
    
    config - Parameterization
  - make
```
public PCARunner make()
```
    Description copied from interface: Parameterizer
    
    Make an instance after successful configuration.
    Note: your class should return the exact type, only this very broad interface should use Object as return type.
    
    Specified by:
    
    make in interface Parameterizer
    
    Returns:
    
    a new instance
