Class SpyAPI

java.lang.Object

java.arthas.SpyAPI

public class SpyAPI
extends Object

 一个adviceId 是什么呢？ 就是一个trace/monitor/watch命令能对应上的一个id，比如一个类某个函数，它的 enter/end/exception 统一是一个id，分配完了就不会再分配。
 
 同样一个method，如果它trace之后，也会有一个 adviceId， 这个method里的所有invoke都是统一处理，认为是一个 adviceId 。 但如果有匹配到不同的 invoke的怎么分配？？
 好像有点难了。。
 
 其实就是把所有可以插入的地方都分类好，那么怎么分类呢？？ 或者是叫同一种匹配，就是同一种的 adviceId? 
 
 比如入参是有  class , method ,是固定的  ,  某个行号，或者 某个
 
 aop插入的叫 adviceId ， command插入的叫 ListenerId？
