lambda表达式又称匿名函数(Anonymous function),其构造了一个可以在其作用范围内捕获变量的函数对象。 lambda表达式实际为一个仿函数functor,编译器后会生成一个匿名类(注:这个类重载了()运算符) 与普通函数指针相比,Lambda表达式可以包含数据成员,也就是说它是可以有状态的。下面举一个简单的例子说明一下: intsum =...
匿名函数(Anonymous Function)是表示“内联”方法定义的表达式。匿名函数本身及其内部没有值或者类型,但是可以转换为兼容的委托或者表达式树类型(了解详情)。匿名函数转换的计算取决于转换的目标类型:如果是委托类型,则转换计算为引用匿名函数所定义的方法的委托;如果是表达式树类型,则转换将计算以对象结构形式表示方法结构的...

lambda-pp.c Implemented lambda-cc. Jul 26, 2014 Synposis LambdaPP is a preprocessor for giving you anonymous functions in C. Examples // for an example the table consists of a string keyed (room) of occupants // stored in a linked list. hashtable_t *table; hashtable_foreach(table, ...
constauto l = [](auto a, auto b, auto c) {};// is equivalent tostructanonymous{template <classT0, classT1, classT2>autooperator()(T0a, T1b, T2c) const { }};在C++ 14中引入的泛型Lambda，它可以使用auto标识符捕获参数。可变泛型Lambda，代码如下：voidprint(){}template <typename Fir...
Lambda是实现了函数调用运算符的匿名类(anonymous class)。对于每一个Lambda,编译器创建匿名类,并定义相应的数据成员存储Lambda捕获的变量。没有捕获变量的Lambda不包含任何含成员变量。一个没有任何成员变量(包括没有虚函数表指针)的类型,在空指针上调用成员函数也不会有任何的问题,因为它的成员函数不会通过this指针访...
