[Boost-users] Does boost have something like this, or does it need one?

6 Mar 2009

      I need something like this:

template <typename Type>
struct Array
{
	private:
		Type *data;
		int size;

	public:
		explicit Array(Type *data, int size) : data(data), size(size) 
		{
			assert(size > 0);
		}

		Type &operator[](int index) const { return data[index]; }

		Type &at(int index) const 
		{
			assert(index > 0 && index < size);
			return data[index];
		}

		Type *getData() const { return data; }

		Type *begin() const { return data; }
		Type *end() const { return data + size; }

		int getSize() const { return size; }
};

But I think boost doesn't have it. boost::array also takes an std::size_t
template parameter but that doesn't work for what I want to do because
I want to be able to pass a function something like this:

void myFunction(const Array<int> &a) { ... }

void main()
{

	int myVec1[6] = { 1,2,3,4,5,6 };
	int myVec2[2] = { 7,8 };

	myFunction(Array<int>(myVec1, 6));
	myFunction(Array<int>(myVec2, 2));

}

I can't do this with boost::array and std::vector allocates and I don't want 
that too. Any help?
