property_tree::get_optional without the template parameter

[harris.pc@…]

Is it possible to call

tree.get_optional<Data>(path) without the <Data> ? Note that Data is the type of the tree's Data.

Would also be nice to be able to get the data as a pointer so that data can be updated in-place instead of get/push.

Like this, implemented as a free function (for the non-const variant):

Data * get_dataptr_optional( Tree & tree, string const& path ) {

if (optional<Tree &> node = tree.get_child_optional(path))

return &node->data();

return NULL;

}

cheers, Paul
