Interface PubrecOutboundInterceptor
-
- 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 PubrecOutboundInterceptor extends Interceptor
Interface for the outbound PUBREC 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
onOutboundPubrec(PubrecOutboundInput, PubrecOutboundOutput)
throws an exception or a call toPubrecOutboundOutput.async(Duration)
times out withTimeoutFallback.FAILURE
, HiveMQ will ignore this interceptor and will:- Log the exception
- Revert the changes to the
ModifiablePubrecPacket
made by the interceptor - Call the next
PubrecOutboundInterceptor
or send the PUBREC to the client if no interceptor is left
