如下class DebugDelete {public:DebugDelete(std::ostream &s = std::cerr) : os(s) {} template <typename T> void operator()(T *p) const { os << "deleting unique_str" << std::endl; delete p; }private:std::ostream &os;}使用方法如下:double *p = new double...
类模板是一种通用的类定义,它可以用于多种类型的数据。类模板使用一个或多个类型参数作为类成员的类型,从而定义了一组可重用的类代码。类模板的语法如下:上面的代码定义了一个类模板myClass,它使用类型参数T来表示类成员的类型。类体中的代码可以使用T来定义成员变量和成员函数。创建类模板的对象时,需要指定T...
Google CTemplate是一个开源的C++模板引擎,可以生成html文件,今天安装出现一些问题,在此将遇到的问题以及解决方式记录下来。 安装 git clone https://github.com/OlafvdSpek/ctemplate.git cd ctemplate ./autogen.sh ./configure make sudo make install(注意带sudo) ...
template <typename T> class Base { public: void someFunction() { if constexpr (std::is_same<T, SpecificType>::value) { // 对SpecificType类型做特殊处理 } else { // 默认处理 } } }; class Derived : public Base<Derived> { // ... }; 在这个例子中,Base::someFunction使用constexpr i...
To make life easy, I encapsulated the process in a class CFindType. To use it, you have to derive your own specialization and implement the virtual function OnMatch: Copy class CMyFindType : public CFindType { protected: virtual BOOL OnMatch(LPCTSTR typName, LPCTSTR asmPath) { // ...
1 template<class a_type> void a_class::a_function(){...} When declaring an instance of a templated class, the syntax is as follows:1 a_class<int> an_example_class; An instantiated object of a templated class is called a specialization; the term specialization is useful to remember beca...

Class Template Specialization Template Class Partial Specialization Template Function Specialization Template Parameters Static Members and Variables Templates and Friends Introduction Many C++ programs use common data structures like stacks, queues and lists. A program may require a queue of customers and a...
In this tutorial, we will learn about function templates in C++ with the help of examples. We can create a single function to work with different data types by using a template.
In member function of class, if type of parameter is the same class or base class, parameter’s private or protected data member can be visited directly in member function, else it is not allowed. Void Dragon::memberfunction( const Dragon & ll); data member of Dragon can be visited direc...
