Getting boost property_tree parent node

Question

I am using boost property_tree in my program. I\'ve set up the tree for using custom path type. What I\'m looking for is getting a specific node\'s parent node id.

Answer 1

You can't.

Boost Ptree nodes are self-contained and do not know about any containing datastructure (it's the the "tree" equivalent of a singly-linked list).

As a best approximation you could look up the child inside the parent, e.g. with something like in C++: boost ptree relative key.

This presumes you always have "a root" available to search in.
