Class AbstractThresholdListener

  • All Implemented Interfaces:
    StatsCollectionListener
    Direct Known Subclasses:
    AbstractFlapListener
    public abstract class AbstractThresholdListener
extends AbstractStatsCollectionListener
    The listener interface for receiving threshold events. The class that is interested in processing a threshold event implements this interface, and the object created with that class is registered with a component using the component's addThresholdListener method. When the threshold event occurs, that object's appropriate method is invoked.
