接口 InterceptHandler

所有已知实现类:

AbstractInterceptHandler

public interface InterceptHandler

This interface is used to inject code for intercepting broker events.

The events can act only as observers.

Almost every method receives a subclass of MqttMessage, except onDisconnect that receives the client id string and onSubscribe and onUnsubscribe that receive a Subscription object.
