It's possible weak_ptr could be used for that, but I have never used it for that purpose. Have you checked out the boost multi_array? It seems that container is very similar to the one your creating. On 6/17/05, Jack Nguyen <bluekite2000@gmail.com> wrote:
Another related question: How do I refer to a subpart of an array pointed to by shared_array. I tried subptr=boost::shared_array<T>(ptr.get()+offset); but this leaves me w/ dangling ptr problem :( Any suggestion???

Its a matrix constructor using pointer indirection. User can then do Matrix<double> M(3,4)//; and 2 arrays will be created, array1 of type *T, size 4 and array2 of type T, size 3*4. array1[0] points to array2[0], array1[1] points to array2[3] so on and so forth. I m having syntax trouble accomplishing the "array1[1] points to array2[3]" part!

It is really hard to tell what you are trying to do from this example. Could you provide an example or description (not necessarily code) of what your matrix structure should look like.

I m trying to build a matrix and m having compile error w/ thei
following codes
mpD=boost::shared_array<boost::shared_array<T> (new boost::shared_array<T>[cols]); mpD[0]=boost::shared_array<T>(new T[rows*cols]); for (int i=1; i<cols;i++) mpD[i]=mpD[0]+i*rows; Seems like there s no match for operator+ Regards,

I currently have
template <typename T> class Vector { private: int Size; boost::shared_array<T> mpD;
void VecAlloc( int size) {
boost::shared_array<T> mpD_temp(new T[size]); mpD=mpD_temp; }
public: Vector() { } Vector(int size) :Size(size) { VecAlloc(size); } }
My question is how do i get rid of boost::shared_array<T> mpD_temp(new T[size]); ???
