Detailed Description

template<class GT, class Node_Attr = Dft_Node_Attr<GT>, class Arc_Attr = Dft_Arc_Attr<GT>, class SN = Dft_Show_Node<GT>, class SA = Dft_Show_Arc<GT>>
struct Aleph::To_Graphviz< GT, Node_Attr, Arc_Attr, SN, SA >

Functor class for generating Graphviz DOT specifications.

A high-level class that traverses a graph and generates a DOT specification for the Graphviz visualization system. The class handles the topological structure while delegating content generation to customizable attribute classes.

Template Parameters

• GT: Graph type (derived from List_Graph)
• Node_Attr: Functor for node attributes. Invoked as: cpp Node_Attr()(g, node, out); // writes to out stream
• Arc_Attr: Functor for arc attributes. Invoked as: cpp Arc_Attr()(g, arc, out); // writes to out stream
• SN: Node filter - only filtered nodes are included
• SA: Arc filter - only filtered arcs are included

Generated Output

For each node:

For each arc:

Usage Example

To_Graphviz<MyGraph> to_dot;
std::ofstream out("graph.dot");
to_dot(my_graph, out);
