事件驱动引擎
|

事件驱动引擎中所有的变量都设置为了私有,这是为了防止不小心

从外部修改了这些变量的值或状态,导致bug。

变量说明
|

__queue:私有变量,事件队列

__active:私有变量,事件引擎开关

__handlers:私有变量,事件处理函数字典
|
||||
|
||||
|
||||
方法说明
|
||||
__run: 私有方法,事件处理线程连续运行用
|
||||
__process: 私有方法,处理事件,调用注册在引擎中的监听函数
|

__onTimer:私有方法,计时器固定事件间隔触发后,向事件队列中存入计时器事件
|

start: 公共方法,启动引擎
|

stop:公共方法,停止引擎
|

register:公共方法,向引擎中注册监听函数

msgpack:性能更高,但通常需要安装msgpack相关工具;

json:性能略低但通用性更好,大部分编程语言都内置了相关的库。

cPickle:性能一般且仅能用于Python,但是可以直接传送Python对象,非常方便。
