C++ Template Specialization (模板特化) 个人理解这个东西说白了就是当模板类(或函数)的类型参数为某特定值时用对应的特化定义代之。 看个例子吧 #include <iostream>usingnamespacestd; template<typename T>structis_void {staticconstboolvalue =false; };/*上面的代码定义了一个简单的模板结构is_void的主版本...

template<typename T> void Test(const T& _t); // cpp文件存放定义及具体的实例化定义,即显式实例化。这样实例化肯定只有一次,并且结构清晰。这种方式适用于模板实例化的具体类型不多的情况。因为如果模板是库文件,不停修改是不方便的。 // fun.cpp file template void Test<int>(const int& _t); templat...

Partial Template Specialization 顾名思义,模版偏特化就是对模版进行特化的意思。 举个例子: namespaceSHFTest { template< classPLA, classPLB > classPLClass { // //一般实现 // public: PLClass() {}; ~PLClass() {}; voidFuncA() {
