java.lang.Object

org.apache.skywalking.apm.plugin.pulsar.common.PulsarProducerInterceptor

All Implemented Interfaces:

InstanceMethodsAroundInterceptor

public class PulsarProducerInterceptor
extends Object
implements InstanceMethodsAroundInterceptor

Interceptor for pulsar producer enhanced instance.
