It seems that c# does not support c++ like templates. For example template <class myType> myType GetMax (myType a, myType b) { return (a>b?a:b); } I want my function to have return type based on its parameters, how can i achieve this in c#? How to use templates in C# EDIT: Can i use object and getType for the almost same purpose? ...
Does anyone have a tactic for dealing with multiple validation rules and templates for those validation rules. Example: I want to have two validation rules (required & data) I want either... One template that can change is display depending on which rule is fired or Two templates, which get displayed depending on which rule is fired ...
I get a compiler warning, that I don't understand in that context, when I compile the "Child.cpp" from the following code. (Don't wonder: I stripped off my class declarations to the bare minuum, so the content will not make much sense, but you will see the problem quicker). I get the warning with VS2003 and VS2008 on the highest warning ...
This code: template <template <typename> class T> class A { }; template <typename T> class B { A<B> x; }; doesn't compile, I suppose since A<B> is interpreted as A<B<T> > within B's scope. So, how do you pass B as a template template parameter within it's scope? ...
template<typename T> class CConstraint { public: CConstraint() { } virtual ~CConstraint() { } template <typename TL> void Verify(int position, int constraints[]) { } template <> void Verify<int>(int, int[]) { } }; Compiling this under g++ gives the following error: Explicit specialization in non-namespace scope 'class CConstrain...
Hi, When creating templates I typically have 3 separate parts (header, body, footer) which I combine to pass a single string to the web-server (CherryPy in this case). My first approach is as follows... from jinja2 import Environment, FileSystemLoader env = Environment(loader=FileSystemLoader('')) tmpl = env.get_template('Body.html'...

Hi, this is a rather basic question (I'm new to Django) but I'm having trouble using a variable set in my view inside my template. If I initialize a string or list inside my view (i.e. h = "hello") and then attempt to call it inside a template: {{ h }} there is neither output nor errors. Similarly, if I try to use a variable inside my ...
Is it possible to get a stringified version of a template argument name? Something like this, if only we were running the preprocessor: template <typename T> struct Named{ const char* name(){ return "Named<" #T ">"; } }; Edit Duplicate. See here http://stackoverflow.com/questions/1488186/stringifying-template-arguments ...
How do I make a class whose interface matches double, but whose templated types do not dynamic cast to double? The reason is that I have a run-time type system, and I want to be able to have a type that works just like double: template<int min_value, int max_value> class BoundedDouble: public double {}; And then use template speciali...
I have a base class called Element, a derived class called Vector, and I'm trying to redefine two virtual functions from Element in Vector. //element.h template <class T> class Element { public: Element(); virtual Element& plus(const Element&); virtual Element& minus(const Element&); }; and in another file //Vector.h #include "Eleme...
Is there a way to get the defered type of a class template parameter ? template <class TPtr> struct foo { typedef TPtr ptr_type; typedef ??? element_type; /* shall be the type of a deferred TPtr*/ }; so foo<const char*>::element_type results in const char, and foo<std::vector<int>::iterator_type>::element_type results in int. ...
I've been tasked with adding a website builder to our suite of applications. Most of our clients are non technical small business owners (brick and mortar stores, mom and pop shops). I've been told that I should be looking at Blogger Template Editor and trying to see if I can make something that fully featured and easy to use. The idea b...

I wondering is there any way to set restrictions on template class? Specify that every type substituted in template must have specific ancestor (realize some interface). template < class B > //and every B must be a child of abstract C class A { public: B * obj; int f() { return B::x + this->obj->f(); } }; Like =>...
I have a superclass which is defined in terms of a few internal types it uses.
