C++ smart pointer const correctness

Question

I have a few containers in a class, for example, vector or map which contain shared_ptr\'s to objects living on the heap.

For example

template 

        

Answer 1

one thing to realize is that:

tr1::shared_ptr is mimicking the functionality of T const * namely what it points to is const, but the pointer itself isn't.

So you can assign a new value to your shared pointer, but I would expect that you wouldn't be able to use the dereferenced shared_ptr as an l-value.
