这样使用 Lambda 表达式就解决了这个匿名内部类的问题,下面是使用 Lambda 表达式来调用这些搜索函数的代码: 上面的示例代码可以在这里下载:RoboCallExample.ziphttp://www.oracle.com/webfolder/technetwork/tutorials/obe/java/Lambda-QuickStart/examples/RoboCallExample.zip java.util.function 包 该包包含了很多常用的...
//the std::function's arg define, must obey to the active datastruct, //for example as follow, arg_1 is const int, arg_2 is int&, arg_3 is const int &, so f2's arg order is "const int + int & + const int &", and also when call f2. auto f2 = std::function<int (c...

C:Lambda的语法介绍 [ capture_clause ] ( parameters ) -> return_type { function_body } Capture Clause(捕获子句):位于方括号 [] 中。这里指定 Lambda 表达式是否捕获外部作用域中的变量以及捕获的方式。捕获方式可以是值捕获、引用捕获、隐式捕获等。 []:不捕获任何外部变量。 [x, &y]:值捕获变量 x...
