Interface UnsubackOutboundInterceptor

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 UnsubackOutboundInterceptor
extends Interceptor
Interface for the UNSUBACK outbound interception.

Interceptors are always called by the same Thread for all UNSUBACK 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.
