Class EdgeParser

java.lang.Object

graphloaders.antlrDotParser.DOTBaseListener

graphloaders.antlrDotParser.EdgeParser

All Implemented Interfaces:

DOTListener, org.antlr.v4.runtime.tree.ParseTreeListener

public class EdgeParser
extends DOTBaseListener

Created by Clemens Hoffmann on 8/11/16.

BaseListener for the second iteration of parsing DOT files. Using the node and subgraph information from the first iteration, all edge statements are inspected and for each edge statement, the corresponding edge / edges (in case of subgraphs) are created.
