Participant (The Adobe Experience Manager SDK 2022.7.8005.20220711T194049Z-220600)

```
@ConsumerType
public interface Participant
```
A Participant participates in a Coordination.
A Participant can participate in a Coordination by registering itself with the Coordination. After successfully registering itself, the Participant is notified when the Coordination is terminated.
If a Coordination terminates normally, then all registered Participants are notified on their ended(Coordination) method. If the Coordination terminates as a failure, then all registered Participants are notified on their failed(Coordination) method.
Participants are required to be thread safe as notification can be made on any thread.
A Participant can only be registered with a single active Coordination at a time. If a Participant is already registered with an active Coordination, attempts to register the Participation with another active Coordination will block until the Coordination the Participant is registered with terminates. Notice that in edge cases the notification to the Participant that the Coordination has terminated can happen before the registration method returns.
