Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface DBManEventListenerI

The listener interface for receiving DBMan events. The class that is interested in processing a DBMan event implements this interface, and the object created with that class is registered with the current DBManEventProviderI. using the DBManEventProviderI's subscribeEvents method. When an event occurs, that object's processDBManEvent method is invoked.

Event handling of the processDBManEvent should be fast and take less than 100ms to return, because all listeners are invoked by a single event dispatch thread. It is strongly recommended to delegate the event handling into another thread and return early, e.g. using a previously initialized Executors.newSingleThreadExecutor().

Usage Examples

To register a listener for changes on Benutzer and Datei Entities:

 //AbstractSync api
 Class[] notifiedClasses = new Class[]{Benutzer.class, Datei.class}
 DBManBOChangeEventFilter filterM = DBManBOChangeEventFilter.getInstance(notifiedClasses)
 try {
    api.getRcl().subscribeEvents(this, filterM)
    //start main consumer loop...
    runMainLoop()
 } finally {
    api.getRcl().unsubscribeEvents(this)
 }
