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.

Constructor & Destructor Documentation

◆ Parser()

ogdf::dot::Parser::Parser ( std::istream &  in)
explicit

Initializes parser class with given input (but does nothing to it).

◆ 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
GGraph whom node is requested.
GAGraphAttributes for given graph, ignored if nullptr.
CClusterGraph for given graph, ignored if nullptr.
dataData about current subgraph.
idIdentifier of requested node.
Returns
Requested node.
