[Boost-users] boost::intrusive_ptr and std::list::iterator

Hello Readers,

I have a question regarding boost::intrusive_ptr and
std::list::iterator. 

I have a std::list<boost::intrusive_ptr<CDataset> > which holds my
datasets.

My question: Is the increment counter of the intrusive_ptr incremented
only by doing the following (assigning a iterator to a dataset)? (I
could try myself, but I do not know what happens with other
compilers/libraries)

typedef List std::list<boost::intrusive_ptr<CDataset> >;
List list;
...
// List holds datasets
...
// Get an iterator:
List::iterator iter = list.begin();

// Is the Increment counter of the dataset incremented by this action? 
// Or does the iterator not necessarily keep a pointer to the dataset
directly?

 
It would be nice, if somebody could answer this question. In the
meantime I try out, what my implementation makes (gcc, linux).

Greetings

Ernst
