PublishAuthorizer (HiveMQ Extension SDK 4.6.4 API)

All Superinterfaces:

Authorizer
```
public interface PublishAuthorizer
extends Authorizer
```
Interface for the PUBLISH authorization.
An Authorizer is 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.

4.0.0, CE 2019.1
