- com.alibaba.dubbo.rpc.RpcContext

```
public class RpcContext
extends Object
```
Thread local context. (API, ThreadLocal, ThreadSafe)
Note: RpcContext is a temporary state holder. States in RpcContext changes every time when request is sent or received. For example: A invokes B, then B invokes C. On service B, RpcContext saves invocation info from A to B before B starts invoking C, and saves invocation info from B to C after B invokes C.
