Function templates for arbitrary STL containers containing arbitrary types.

I have an arbitrary STL container C, which contains elements of an arbitrary type T. I want to create an std::vector that has a copy of all the elements. What is the cleanest way to do this? template <typename C> void myfunction(C container){ /*Derive the type T of elements within the container*/ std::vector<T> mystack; ...

Can the template parameters of a constructor be explicitly specified?

A constructor of a class can be a template function. At the point where such a constructor is called, the compiler usually looks at the arguments given to the constructor and determines the used template parameters from them. Is there also some syntax to specify the template parameters explicitly? A contrived example: struct A { tem...

Template specialization within template definition: is this supported for all compilers or standard usage?

This compiled on VS 2008, but it seems like non-standard usage of templates. template <class T> class Foo { public: void bar(Foo<int> arg) { // do some stuff here } // more code ... }; Is there an issue since the template specialization Foo<int> is contained within the definition of its own template class? ...

User Defined Class as a Template Parameter

Hi, I' m implementing a custom STL map. I need to make sure that any data type (basic or user defined) key will work with it. I declared the Map class as a template which has two parameters for the key and the value. My question is if I need to use a string as the key type, how can I overload the < and > operators for string type keys o...

Specify template parameters at runtime

Consider the following template class class MyClassInterface { public: virtual double foo(double) = 0; } class MyClass<int P1, int P2, int P3> : public MyClassInterface { public: double foo(double a) { // complex computation dependent on P1, P2, P3 } // more methods and fields (dependent on P1, P2, P3) } The template para...

Where are the function address literals in c++?

UPDATE: After some additional reading, what I really wanted was guaranteed early binding (which should translated to an immediate call for non-virtual functions and non-PIC code), which can be done by passing a (member) function as a template parameter. The problem I had was that gcc < 4.5 and icc 11.1 can generate some funky instruction...

Optimization of a c++ matrix/bitmap class

I am searching a 2D matrix (or bitmap) class which is flexible but also fast element access. The contents A flexible class should allow you to choose dimensions during runtime, and would look something like this (simplified): class Matrix { public: Matrix(int w, int h) : data(new int[x*y]), width(w) {} void SetElement(int...

Is the use of union in this matrix class completely safe?

Unions aren't something I've used that often and after looking at a few other questions on them here it seems like there is almost always some kind of caveat where they might not work. Eg. structs possibly having unexpected padding or endian differences. Came across this in a math library I'm using though and I wondered if it is a total...
