ConnackOutboundInterceptor (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 ConnackOutboundInterceptor
extends Interceptor
```
Interface for the outbound CONNACK interception.
Interceptors are always called by the same Thread for all 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.
When the method onOutboundConnack(ConnackOutboundInput, ConnackOutboundOutput) throws an exception or a call to ConnackOutboundOutput.async(Duration) times out with TimeoutFallback.FAILURE, then the connection will be closed by the broker without another packet being sent to the client.
