Java集合——集合框架Iterator接口 1.集合输出 很多情况下我们需要把集合的内容进行输出,也就是遍历集合。 遍历集合的方式有以下几种: 1.Iterator 2.ListIterator 3.Enumeration(枚举方式,比较老一般不用) 4.foreach 5.传统for循环 其中Iterator的使用率最高。 publicclassCollectionIterator {/***@paramargs*/publi...

因此我们仅仅要求 visitor 定义 output_type。输入尽管用模板。 然后是如何解决连接:比如我们需要连接函数 f 和 g, 1 2 auto out = g (f (in)) ; auto out = std::make_pair (f (in), g (in)) ; 我们也可能喜欢这种风格, 1 2 f (in, mid) ; g (mid, out) ; f (in, out.first) ; ...
