java.util.EventListener
```
public interface DataQueueListener
extends java.util.EventListener
```
Provides an interface for receiving DataQueue events.
Note: Only actions performed via the Java object that implements this interface will fire events to listeners. Data queue accesses performed by other means (such as by calling system APIs or CL commands) do not fire events to listeners.
