[openvrml-develop] shared_ptr<scope> and scope*

[Murashov G. <Mur...@se...>]

Hi.

Could you tell me, please, how function
openvrml::node_type::create_node() is supposed to be used?
I'm asking, because I'm little bit confused that one get shared_ptr<
scope > as parameter and openvrml::node use shared_ptr inside, but
node::scope() and scene::root_scope() return scope& and scope*.
Is it bug?

Another question: everywhere, working with object openvrml::node,
intrusive_ptr is used, but openvrml::scope::find_node() returns
openvrml::node*. Although in this case safe work is possible, I think
that it is not in right way.

Gleb.
