Hello, I thought that I wanted to template function specialization, but this stackoverflow article makes me think that I should really by doing function overloading. However, I'm just not seeing how I could achieve what I want. I have been able to achieve the goal with a class template specialization, but I don't like the fact that I h...
I need bit counter utility in C++ that is capable of counting number of the most significant bit in a numeric constant value and present this number as compile-time constant. Just to make everything clear - number of the most significant bit for a set of numeric values: 255 => 8 (11111111b) 7 => 3 (111b) 1024 => 11 (1000000000...

Hello! Is is possible to make compilation-time Type -> Enum Series mapping? Illustrating with an example: Let's say, I have some Type and a enumerated value: typedef int Type; enum Enumerated { Enum1, Enum2, Enum3, Enum4 }; and now I somehow state the following: "let's associate Enum1 and Enum4 with type Type (don't know how to im...
What is the difference between specialization and instantiation in context of C++ templates. From what I have read so far the following is what I have understood about specialization and instantiation. template <template T> struct Struct { T x; }; template<> struct Struct <int> //specialization { //code }; int main() { S...
Suppose I have arbitrary template method, which could receive parameters by value and by const reference (obviously, for trivial types and for objects accordingly). How is this situation handled when writing template function prototypes? I could make something like: template <typename T> void Foo(T value) { // Do something. } temp...
In my current project i'm using several textbox controls whose content is filled from objects which are coming from a database. The object uses validation to validate the correct insertion of the text. When i want to show a validation error (i.e. the text has to many characters) i have to add some binding options to the text property li...
I have a struct which indicates a trait: template<typename T> struct FooTraits { static const NEbool s_implementsFoo = false; }; And I can specialize it with a class, thus: class Apple {}; template<> struct FooTraits< Apple > { static const NEbool s_implementsFoo = true; }; However currently I cannot use FooTraits if the c...
I wrote a template function to compare two variables: template <class t> int compare(const t &a, const t &b) { if(a>b) return 1; if (a<b) return -1; return 0; } int main(int argc, const char *argv[]) { cout << compare("hi","world"); return 0; } I get the following error ../src/templates.cpp: In function ‘int main(int...

On my C++ project, I recently stumbled upon a little problem: Templates. I declared a class, Data in my header file (which is shared by each .cpp), and gave it a template function. I implemented it in data.cpp. I soon remembered how templates are compiled on the spot, when they are referred to, and this breaks the declaration/implementa...
Let me say we have a simple programming task. But for the sake of clarity I start with few code samples. First of all we written a some kind of data container class but for the purposes of task no matter what the class is. We just need it to behave const-correct. class DataComponent { public: const std::string& getCaption() const { ...

One very annoying thing with strict MVC is that you can make the smallest processing in template. While it's usually a good practice, in this case it gets in the way: I make a for loop on a queryset of a lot of objects and display some attributes; Attributes are properties, making heavy processing (I don't want to trigger them twice). ...
Ok, I should simply tell that I want to make a base Singleton class that I can inherit from, and the way I want to achieve that is by a template. In order to avoid memory leaks, I do not use directly a pointer to the instance, but a private class that will handle deleting the pointer. Here is my actual code (not working) : template <t...
For example, I have a wide variety of needs for templates, like in creating project plans, project specifications, requirements etc. But I have never created my own forms before, so it really helps to see other practical/actual examples. Is there a good central resource for ms word templates for programmers/programming? I have just st...
