SynchronizationVetoable (Camel :: API 3.16.0 API)

All Superinterfaces:

Synchronization
```
public interface SynchronizationVetoable
extends Synchronization
```
A vetoable Synchronization.
When using Synchronization they are normally executed when the Exchange complete at the end. If the Exchange is processed asynchronously the Synchronization will be handed over to the next thread. This ensures for example the file consumer will delete the processed file at the very end, when the Exchange has been completed successfully.
However there may be situations where you do not want to handover certain Synchronization, such as when doing asynchronously request/reply over SEDA or VM endpoints.
