关于template 的23个问题
发现新大陆。曾经慢慢才知道的东西。原来有个集中营：
看看updated, 处理方式是这么的好
| 35.1 | " id="link-to-faq-35_1" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">What‘s the idea behind templates? |
| 35.2 | What‘s the syntax / semantics for a "class template"? |
| 35.3 | " id="link-to-faq-35_3" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">What‘s the syntax / semantics for a "function template"? |
| 35.4 | How do I explicitly select which version of a function template should get called? |
| 35.5 | What is a "parameterized type"? |
| 35.6 | " id="link-to-faq-35_6" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">What is "genericity"? |
| 35.7 | My template function does something special when the template type T is int or std::string; how do I write my template so it uses the special code when T is one of those specific types? |
| 35.8 | Huh? Can you provide an example of template specialization that doesn‘t use foo and bar? |
| 35.9 | " id="link-to-faq-35_9" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">But most of the code in my template function is the same; is there some way to get the benefits of template specialization without duplicating all that source code? |
| 35.10 | " id="link-to-faq-35_10" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">All those templates and template specializations must slow down my program, right? |
| 35.11 | " id="link-to-faq-35_11" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">So templates are overloading, right? |
| 35.12 | " id="link-to-faq-35_12" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">Why can‘t I separate the definition of my templates class from its declaration and put it inside a .cpp file? |
| 35.13 | How can I avoid linker errors with my template functions? Updated! |
| 35.14 | " id="link-to-faq-35_14" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">How does the C++ keyword export help with template linker errors? Updated! |
| 35.15 | How can I avoid linker errors with my template classes? Updated! |
| 35.16 | " id="link-to-faq-35_16" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">Why do I get linker errors when I use template friends? |
| 35.17 | How can any human hope to understand these overly verbose template-based error messages? |
| 35.18 | Why am I getting errors when my template-derived-class uses a nested type it inherits from its template-base-class? |
| 35.19 | Why am I getting errors when my template-derived-class uses a member it inherits from its template-base-class? |
| 35.20 | Can the previous problem hurt me silently? Is it possible that the compiler will silently generate the wrong code? |
| 35.21 | " id="link-to-faq-35_21" style="color:rgb(59,102,153); background-color:transparent; text-decoration:none">How can I create a container-template that allows my users to supply the type of the underlying container that actually stores the values? |
| 35.22 | Follow-up to previous: can I pass in the underlying structure and the element-type separately? |
| 35.23 | Related: all those proxies must negatively reflect on the speed of my program. Don‘t they? |
