handy源码阅读（二）：EventsImp类

EventsImp用于完成事件的处理。

class EventsImp {

  EventBase* base_;

  PollerBase* poller_;

  std::atomic<bool> exit_;

  int wakeupFds_[];

  int nextTimeout_;

  SafeQueue<Task> tasks_;

  std::map<TimerId, TimerRepeatable> timerReps_;

  std::map<TimerId, Task> timers_;

  std::atomic<int64_t> timerSeq_;

  std::map<int, std::list<IdleNode>> idleConns_;

  std::set<TcpConnPtr> reconnectConns_;

  bool idleEnabled;

  EventsImp(EventBase* base, int taskCap);

  ~EventImp();

  void init();

  void callIdles();

  IdleId registerIdle(int idle, const TcpConnPtr& con, const TcpCallBack& cb);

  void unregisterIdle(const IdleId& id);

  void updateIdle(const IdleId& id);

  void handleTimeouts();

  void refreshNearest(const TimerId* tid = NULL);

  void repeatableTimeout(TimerRepeatable*  tr);

  EventBase& exit();

  bool exited();

  void safeCall(Task&& task);

  void loop();

  void loop_once(int waitMs);

  void wakup();

  bool cancel(TimerId timerid);

  TimerId runAt(int64_t milli, Task&& task, int64_t interval);

};

可以看出类EventsImp有成员变量：任务队列 SafeQueue<Task> tasks_ 见此链接：https://www.cnblogs.com/sssblog/p/11552037.html
