TemplateInstantiation 類別會與 MatchEvent、MatchEventInMemberFunction、MatchEventStack 和MatchEventStackInMemberFunction 函式搭配使用。 使用它來比對 TEMPLATE_INSTANTIATION 事件。 語法 C++ 複製 class TemplateInstantiation : public Activity { public: enum class Kind { CLASS = TEMPLATE_INSTANTIATION_KIND_...

1、请使用member function templates(成员函数模版) 生成“可接受所有兼容类型”的函数。 2、如果你声明member templates用于“泛化copy构造”或“泛化assignment操作”,你还是需要声明正常的copy构造函数和copy assognment操作符。 46、需要类型转换时,请为模版定义非成员函数(Define non-member functions inside templates...
