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_[2];
  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
