[LLVMdev] How to implement list in llvm

[Cristianno Martins]

Hi,

I guess you could use a template with a std::vector: you don't need to define right away the type, if you create a template of it. 

It should look something like that:

template<class B> class List {
std::vector<B> myList;
void insert (int pos, B elem);
}

template <class B> 
void List::add (int pos, B elem) { 
  myList.insert(myList.begin()+pos, elem);
}

Then, wherever you'll use this class, you should define for which class B your class List should match (such as "List<int> intList;" or "List< std::vector<long> > longVectors;").
