Detailed Description

DOT format parser class.

Provides methods for reading graphs in the DOT format. This class is actually just a wrapper/composer for Ast and Lexer classes.

requestNode()

node ogdf::dot::Parser::requestNode	(	Graph &	G,
		GraphAttributes *	GA,
		ClusterGraph *	C,
		const SubgraphData &	data,
		const std::string &	id
	)

Perfoms a node query, returning node for given attribute.

Returns a node with given id in a graph. If node is requested for the first time then Graph::newNode is called and node is initialized with default attributes and placed in proper cluster (through data).

Parameters

G	Graph whom node is requested.
GA	GraphAttributes for given graph, ignored if nullptr.
C	ClusterGraph for given graph, ignored if nullptr.
data	Data about current subgraph.
id	Identifier of requested node.

Returns

Requested node.
