Constructor & Destructor Documentation

◆ DiagramExplainer()

vg::DiagramExplainer::DiagramExplainer ( )

Construct a DiagramExplainer that will save a diagram to one or more files.

◆ ~DiagramExplainer()

vg::DiagramExplainer::~DiagramExplainer ( )

Close out the files being explained to.

Member Function Documentation

◆ add_edge()

void vg::DiagramExplainer::add_edge	(	const std::string &	a_id,
		const std::string &	b_id,
		const annotation_t &	annotations = `{}`
	)

Add an edge. Optionally give it the given annotation, which must be pre-escaped. The edge is assumed not to exist already.

◆ add_globals()

void vg::DiagramExplainer::add_globals ( const annotation_t & annotations )

Add global annotations (like rankdir)

◆ add_node()

void vg::DiagramExplainer::add_node	(	const std::string &	id,
		const annotation_t &	annotations = `{}`
	)

Add a node. Optionally give it the given annotation, which must be pre-escaped. The node is assumed not to exist already

◆ ensure_edge()

void vg::DiagramExplainer::ensure_edge	(	const std::string &	a_id,
		const std::string &	b_id,
		const annotation_t &	annotations = `{}`
	)

Add an edge. Optionally give it the given annotation, which must be pre-escaped. Deduplicates multiple calls with the same IDs in the same order.

◆ ensure_node()

void vg::DiagramExplainer::ensure_node	(	const std::string &	id,
		const annotation_t &	annotations = `{}`
	)

Add a node. Optionally give it the given annotation, which must be pre-escaped. Deduplicates multiple calls with the same ID.

◆ for_each_edge()

void vg::DiagramExplainer::for_each_edge ( const std::function< void(const edge_ref_t &)> & iteratee ) const

protected

Loop over all the edges, across all kinds of storage.

◆ suggest_edge()

void vg::DiagramExplainer::suggest_edge	(	const std::string &	a_id,
		const std::string &	b_id,
		const std::string &	category,
		double	importance,
		const annotation_t &	annotations = `{}`
	)

Add an optional edge. Optionally give it the given annotation, which must be pre-escaped. Only the k most important edges in each category will actually render

◆ write_annotations()

void vg::DiagramExplainer::write_annotations	(	std::ostream &	out,
		const annotation_t &	annotations
	)		const

protected

Save the annotations for a node or edge, if any.

◆ write_connected_components()

void vg::DiagramExplainer::write_connected_components ( ) const

protected

Write each connected component to a different file.

◆ write_edge()

void vg::DiagramExplainer::write_edge	(	std::ostream &	out,
		const std::string &	a_id,
		const std::string &	b_id,
		const annotation_t &	annotations
	)		const

protected

Write out an edge.

◆ write_globals()

void vg::DiagramExplainer::write_globals	(	std::ostream &	out,
		const annotation_t &	annotations
	)		const

protected

Write out globals.

◆ write_node()

void vg::DiagramExplainer::write_node	(	std::ostream &	out,
		const std::string &	id,
		const annotation_t &	annotations
	)		const

protected
