Interface PubcompInboundInterceptor
-
- 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 PubcompInboundInterceptor extends Interceptor
Interface for the inbound PUBCOMP 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
onInboundPubcomp(PubcompInboundInput, PubcompInboundOutput)
throws an exception or a call toPubcompInboundOutput.async(Duration)
times out withTimeoutFallback.FAILURE
, HiveMQ will ignore this interceptor and will:- Log the exception
- Revert the changes to the
ModifiablePubcompPacket
made by the interceptor - Call the next
PubcompInboundInterceptor
or send the PUBCOMP to the server if no interceptor is left
