Detailed Description

Export a dfx::Graph::Controller as a Graphviz DOT string.

The exporter references the provided graph controller; it does not take ownership and assumes the controller outlives the exporter instance.

Typicall usage:

auto const result = dfx::Graph::Exporter::Dot(graph).process();

Note

This class is a pure formatter: it does not perform I/O.

defaultStyle()

Style dfx::Graph::Exporter::Dot::defaultStyle ( )

static

Returns the default dot format style.

process()

std::string dfx::Graph::Exporter::Dot::process

const

Generate the DOT representation of the graph.

The output contains:

• A directed graph (digraph) named dfx_graph

• Record-shaped nodes with labeled input/output ports (when present)
• Edges connecting output ports to input ports for each channel
