SubackOutboundInterceptor (HiveMQ Extension SDK 4.27.0 API)

All Superinterfaces:

Interceptor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface SubackOutboundInterceptor
extends Interceptor
```
Interface for the SUBACK outbound interception.
Interceptors are always called by the same Thread for all SUBACK messages from the same client.
If the same instance is shared between multiple clients it can be called in different Threads and must therefore be thread-safe.

4.3.0, CE 2020.1
