... How about:
mymap b; b[a][b][c] = 2; // assigns value 2 to node at a/b/c
The way I'm figuring this would work is:
* Accessing a child node with operator[] always succeeds but may point to a "ghost" node that doesn't actually exist. * Assignment to a node always succeeds, the node gets created if required. ... int i = mymap["fee"]["far"]["thumb"].get(3);
returns 3 if there is no data.
Just my 2 cents, this is just how it's implemented it in jsoncpp (which doesn't even attempt to do half of what the proposed library do): http://jsoncpp.sourceforge.net/ http://jsoncpp.sourceforge.net/class_json_1_1_value.html To my knowledge JDOM and TinyXML also provides a similar mecanism. So you may have put your finger on something, Baptiste.
