- All Implemented Interfaces:
GraphConstants
public class DotParser extends java.lang.Object implements GraphConstants
This class parses input in DOT format, and builds the datastructures that are passed to it. It is NOT 100% compatible with the DOT format. The GraphNode and GraphEdge classes do not have any provision for dealing with different colours or shapes of nodes, there can however, be a different label and ID for a node. It also does not do anything for labels for edges. However, this class won't crash or throw an exception if it encounters any of the above attributes of an edge or a node. This class however, won't be able to deal with things like subgraphs and grouping of nodes.- Version:

DotParser
public DotParser(java.io.Reader input, FastVector nodes, FastVector edges)
Dot parser Constructor- Parameters:
input
- - The input, if passing in a string then encapsulate that in String reader objectnodes
- - Vector to put in GraphNode objects, corresponding to the nodes parsed in from the inputedges
- - Vector to put in GraphEdge objects, corresponding to the edges parsed in from the input

Method Detail
-
parse
public java.lang.String parse()
This method parses the string or the InputStream that we passed in through the constructor and builds up the m_nodes and m_edges vectors- Returns:
- - returns the name of the graph
-
writeDOT
public static void writeDOT(java.lang.String filename, java.lang.String graphName, FastVector nodes, FastVector edges)
This method saves a graph in a file in DOT format. However, if reloaded in GraphVisualizer we would need to layout the graph again.- Parameters:
filename
- - The name of the file to write in. (will overwrite)graphName
- - The name of the graphnodes
- - Vector containing all the nodesedges
- - Vector containing all the edges
