类 Context

java.lang.Object
com.alibaba.csp.sentinel.context.Context
直接已知子类:
NullContext
public class Context extends Object
This class holds metadata of current invocation:
  • the EntranceNode: the root of the current invocation tree.
  • the current Entry: the current invocation point.
  • the current Node: the statistics related to the Entry.
  • the origin: The origin is useful when we want to control different invoker/consumer separately. Usually the origin could be the Service Consumer's app name or origin IP.

Each SphU#entry() or SphO#entry() should be in a Context, if we don't invoke ContextUtil#enter() explicitly, DEFAULT context will be used.

A invocation tree will be created if we invoke SphU#entry() multi times in the same context.

Same resource in different context will count separately, see NodeSelectorSlot.
