Interface LifecycleListener

public interface LifecycleListener

A callback interface that listens to specific lifecycle events triggered when Spoon starts and stops. Listeners are loaded dynamically by PDI. In order to register a listener with Spoon, a class that implements this interface must be placed in the "org.pentaho.di.core.listeners.pdi" package, and it will be loaded automatically when Spoon starts.
