org.kahina.core.behavior
Class KahinaBehavior<T extends KahinaObject>

java.lang.Object
  org.kahina.core.behavior.KahinaBehavior<T>

Type Parameters:

T - a subclass of KahinaObject

All Implemented Interfaces:

KahinaListener

Direct Known Subclasses:

KahinaDAGBehavior, KahinaTreeBehavior

public class KahinaBehavior<T extends KahinaObject>
extends Object
implements KahinaListener

The generic ancestor class of all behavior classes.

Behaviors are Kahina's way of defining the application-specific behavior of complex components such as trees. They usually determine how a complex object is constructed and how it reacts to incoming KahinaEvents. A typical use case is LogicProgrammingTreeBehavior for control flow trees in logic programming.

This class is generic and can be specialized for any subclass of KahinaObject.

In an application, the user will usually want to inherit from a specialized variant such as KahinaTreeBehavior. By default, a KahinaBehavior implements the KahinaListener interface, but it does not register itself with the event system. For that purpose, implementations should use the KahinaRunner.getControl().registerListener mechanism.

Field Summary

protected KahinaInstance	kahina The KahinaInstance this behavior is connected to
protected T	object The KahinaObject that is being controlled by this behavior

Constructor Summary

KahinaBehavior(T object, KahinaInstance kahina)
Class constructor specifying the controlled object and the KahinaInstance that it is connected to.

Method Summary

void	processEvent(KahinaEvent e) Does not react to any event by default; is overridden by implementations.
