在GraphX中,核心操作都是被优化过的,组合核心操作的定义在GraphOps中。 由于Scala隐式转换,定义在GraphOps的操作可以在Graph的成员中获取。例如:我们计算图中每个顶点的入度.(该方法是定义在GraphOps) val graph:Graph[(String,String),String] // Use the implicit GraphOps.inDegrees operator ...

简单解释代码中的{char 0xa0},这是 SMCL(Stata Markup and Control Language) 语言,是 Stata 中的一种标记语言, help 文档大都是用它编写的。char表示字符,0xa0是 ASCII 编码的空格。所以这里实际是“偷梁换柱”,将 x 轴刻度每隔 5 个单位换为空格,这样绘制出来的图就实现了肉眼不可见的空白。
