public class OEHeuristicRuntime
extends AbstractHeuristic

Search algorithm heuristic for the ontology engineering algorithm. The heuristic has a strong bias towards short descriptions (i.e. the algorithm is likely to be less suitable for learning complex descriptions).

Method Detail

init

public void init()
          throws ComponentInitException

Description copied from interface: Component

Method to be called after the component has been configured. Implementation of components can overwrite this method to perform setup and initialisation tasks for this component.

Specified by:

init in interface Component

Overrides:

init in class AbstractHeuristic

Throws:

ComponentInitException - This exception is thrown if any exceptions occur within the initialisation process of this component. As component developer, you are encouraged to re-throw occurring exception as ComponentInitException and giving an error message as well as the actually exception by using the constructor ComponentInitException(String, Throwable).
