EventHubOutput Interface
Implements
public interface EventHubOutput implements java.lang.annotation.Annotation
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();
}
