EventHubOutput Interface

Definition

Place this on a parameter whose value would be published to the event hub. The parameter type should be OutputBinding, where T could be one of:

  • Any native Java types such as int, String, byte[]
  • Any POJO type

The following example shows a Java function that writes a message to an event hub:

@FunctionName("sendTime")
@EventHubOutput(name = "event", eventHubName = "samples-workitems", connection = "AzureEventHubConnection")
 public String sendTime(
    @TimerTrigger(name = "sendTimeTrigger", schedule = "0 */5 * * * *") String timerInfo
 ) {
     return LocalDateTime.now().toString();
 }
public interface EventHubOutput implements Annotation
Implements
java.lang.annotation.Annotation
