Constructor & Destructor Documentation

◆ Edge()

jlm::util::graph::Edge::Edge	(	Port &	from,
		Port &	to,
		bool	directed
	)

private

Definition at line 1238 of file GraphWriter.cpp.

◆ ~Edge()

jlm::util::graph::Edge::~Edge ( )

overridedefault

Member Function Documentation

◆ getDirection()

std::string_view jlm::util::graph::Edge::getDirection ( ) const

Determines which sides on the edge should have arrow styling. A directed edge always has an arrow head. If arrow head or arrow tail styling is given, the direction reflects that.

Returns: the direction value, as expected by the GraphViz "dir" attribute.

Definition at line 1309 of file GraphWriter.cpp.

◆ GetFrom()

Port & jlm::util::graph::Edge::GetFrom ( )

Gets the port being pointed to Even if the edge is non-directed, the from/to order can matter for layout.

Definition at line 1261 of file GraphWriter.cpp.

◆ GetGraph()

Graph & jlm::util::graph::Edge::GetGraph ( )

overridevirtual

Gets a reference to the graph this GraphElement belongs to

Implements jlm::util::graph::GraphElement.

Definition at line 1254 of file GraphWriter.cpp.

◆ GetIdPrefix()

const char * jlm::util::graph::Edge::GetIdPrefix ( ) const

overridevirtual

Gets a short string that will serve as the base for a unique ID. This base should be a valid C-like identifier.

Returns: a string, such as "node", "i", "o", "graph"

Implements jlm::util::graph::GraphElement.

Definition at line 1248 of file GraphWriter.cpp.

◆ GetOtherEnd()

Port & jlm::util::graph::Edge::GetOtherEnd ( const Port & end )

Given one end of the edge, returns the port on the opposite side of the edge.

Definition at line 1279 of file GraphWriter.cpp.

◆ GetTo()

Port & jlm::util::graph::Edge::GetTo ( )

Gets the port being pointed from. Even if the edge is non-directed, the from/to order can matter for layout.

Definition at line 1267 of file GraphWriter.cpp.

◆ IsDirected()

bool jlm::util::graph::Edge::IsDirected ( ) const

Returns: true if this edge is directed, false otherwise

Definition at line 1273 of file GraphWriter.cpp.

◆ OutputDot()

void jlm::util::graph::Edge::OutputDot	(	std::ostream &	out,
		size_t	indent
	)		const

Outputs the edge in dot format.

Definition at line 1324 of file GraphWriter.cpp.

◆ outputJson()

void jlm::util::graph::Edge::outputJson	(	std::ostream &	out,
		size_t	indent
	)		const

Outputs the edge as an "id": key and json object.

Definition at line 1354 of file GraphWriter.cpp.

◆ SetArrowHead()

void jlm::util::graph::Edge::SetArrowHead ( std::string arrow )

Customizes the look of the edge at the head end. For a normal arrow, use "normal". Other common options are "box", "diamond" and "dot". Prefix the string with "o" to get outline only. Prefix with "l" or "r" to only get one half. Concatenate multiple strings to get longer arrows, with the tipmost arrow listed first. For full a description of the grammar, see https://graphviz.org/doc/info/arrows.html

Parameters

arrow a string describing the look of the edge head.

Definition at line 1296 of file GraphWriter.cpp.

◆ SetArrowTail()

void jlm::util::graph::Edge::SetArrowTail ( std::string arrow )

Customizes the look of the edge at the tail end.

Parameters

arrow a string describing the look of the edge tail.

See also: Edge::SetArrowHead() for a short description of the grammar

Definition at line 1302 of file GraphWriter.cpp.

◆ SetStyle()

void jlm::util::graph::Edge::SetStyle ( std::string style )

Sets the style of the edge

See also: Edge::Style for a list of possible styles

Definition at line 1290 of file GraphWriter.cpp.
