工欲善其事必先利其器，磨刀不误砍柴工
最近打算去深读源码，感觉不画图去分析源码根本理不清，也说不清
UML是分析类和类的关系，具体的类内部貌似没有图形机制，没有条件就创造条件呗
借此机会本人自定义一套图形绘图表示规范，并恬不知耻地称为捷型图
目的为了明确各种元素的图形表示，来表述与分析源码具体运行逻辑
为了避免每张图都加个图例，这里成文统一描述一下
一、常用表示
1.访问限制类型
无形状限定，修饰中(左上角)见色如见人
访问限制类型.png
2.常见修饰符
三角形，放在左上角
常见修饰符.png
3.类相关
类相关.png
4.方法与变量
成员及方法.png
5.关联线
表述无歧义情况下箭头,数字可略
关联线.png
6.uml线
uml.png
二.其他不常用:
1.第一组
不常用的组合1.png
//待续...
三、几个小例子说明一下
1.类例子
ActivityThread是一个public final的普通类
ApplicationThread 是一个private的内部类 , 并处于 ActivityThread中
例子.png
2.方法与变量例子
l方法与变量.png
3.sendBroadcast的第一层关系
在Activity中调用sendBroadcast，会调用ContextWrapper的sendBroadcast方法
sendBroadcast会使用ContextWrapper的成员变量mBase的sendBroadcast方法
而mBase实际上来源于ContextImpl，而ContextImpl是一个Context类，
ContextImpl的sendBroadcast方法调用ActivityManagerNative.getDefault().broadcastIntent发送广播
这样就将工作焦点指向ActivityManagerNative，可以进行第二层的绘制，也就是分析
ActivityManagerNative，上面的四行话解释和下面的图你更喜欢哪个?
成年人的世界没有单选题，当然选择都要，图文结合，更能形象说明
广播第一层.png
4.捷型图示例
下图是基于下面类绘制的图形，有什么好的意见或建议欢迎留言，
目前使用processon在线绘图工具，以后有时间开发个小软件来绘制感觉挺不错，
再加个一键生成什么的就更棒了...
