public abstract class AbstractFlapListener
extends AbstractThresholdListener

The listener interface for receiving flap events. The class that is interested in processing a flap event implements this interface, and the object created with that class is registered with a component using the component's addFlapListener method. When the flap event occurs, that object's appropriate method is invoked.
