README The tree.hh library for C++ provides an STL-like container class for n-ary trees. Various types of iterators are provided (post-order, pre-order, and others). Where possible the access methods are compatible with the STL or alternative algorithms are available. This implementation is revised from Kasper Peeters's implementation.(http://www.aei.mpg.de/~peekas/tree/) Compared to that, this implementation has simpler and clearer interfaces. Several new interfaces are also added. Usage: Create a tree whose node is string: tree<string> tr; Set root: tr.set_root("a");//insert Append child: tree<string>::pre_order_iterator pos_b1=tr.append_child(tr.root(), "b1"); tree<string>::pre_order_iterator pos_c1=tr.append_child(pos_b1, "c1"); Traverse: tree<string>::pre_order_iterator pre_iter = tr.root(); for(; pre_iter!=tr.end_pre_order_iterator(tr.root());++pre_iter) { //get depth cout<<"+"; for(int i=0;i<tr.depth(pre_iter);i++) cout<<"+"; cout<<*pre_iter<<endl; } Other features: See tree.hh
