C++: typedef-ing STL

Instead of using

std::vector<Object> ObjectArray;

I would like it to be

MyArray<Object> ObjectArray;

with all the std::vector methods preserved. (like push_back(), reserve(), ...etc)

However, using

typedef std::vector MyArray;

won't work. Should I use template instead? How?

Thanks in advance.

From stackoverflow

• What you would really want is a templated typedef. Unfortunately those are not supported in the current version of C++, but they will be added in C++0x.

  For now, here's a possible workaround:

  template<class T> struct My {
      typedef std::vector<T> Array;
  };
  
  My<Object>::Array ObjectArray
  

  Whether or not that is better than simply using std::vector directly, I'll leave to you to decide.

  Thomas : Greg, thanks for fixing my syntax. Can you tell that I've been using a lot of Java lately? ;)

• Another way:

  #include <vector>
  
  template <typename T>
  struct MyArray
      :std::vector<T>
  {
  };
  
  void func()
  {
      MyArray<int> my;
  
      my.push_back(5);
  
      MyArray<int>::iterator i;
  }
  

  Compiles for me, but you may find that some things available in vector<> need to be "pulled up" into MyArray.
