Example 11 with EnhancedInstance

use of org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.EnhancedInstance in project incubator-skywalking by apache.

the class EnqueueInterceptor method beforeMethod.

     * Here is the process about how to trace the async function.
     *
     * 1. Storage `Request` object into `RealCall` instance when the constructor of `RealCall` called.
     * 2. Put the `RealCall` instance to `CallBack` instance
     * 3. Get the `RealCall` instance from `CallBack` and then Put the `RealCall` into `AsyncCall` instance
     *    since the constructor of `RealCall` called.
     * 5. Create the exit span by using the `RealCall` instance when `AsyncCall` method called.
