Detailed Description

template<class GT, typename Key, class Convert, class SA = Dft_Show_Arc<GT>>
class Aleph::Graph_To_Tree_Node< GT, Key, Convert, SA >

Functor class to convert a tree graph to Tree_Node structure.

Provides a callable interface for converting spanning trees from graph representation to Tree_Node<Key> representation.

This class version offers more flexibility than the free function, allowing the arc filter to be configured at construction time.

Template Parameters

• GT: Graph type (derived from List_Graph)
• Key: Data type to store in tree nodes
• Convert: Functor class with operator()(gnode, tnode) that copies data from graph nodes to tree nodes
• SA: Arc filter class (default: show all arcs)

Usage Example

struct MyConvert {
  void operator()(Graph::Node* gn, Tree_Node<int>* tn) {
    tn->get_key() = gn->get_info().id;
  }
};
 
Graph_To_Tree_Node<Graph, int, MyConvert> converter;
auto* root = converter(g, start_node);

inline

Convert a tree graph to Tree_Node structure.

Parameters

g	The tree graph to convert (must be acyclic)
groot	Node to use as the tree root
conv	Converter functor instance

Returns

Root of the new Tree_Node<Key> tree

Exceptions

std::domain_error	If the graph is not acyclic
std::bad_alloc	If memory allocation fails
