Method Detail

readUndirected

public Graph<Edge> readUndirected(File f)
                           throws IOException

Description copied from class: GraphReaderAdapter

Reads in the graph from the provided file

Specified by:

readUndirected in interface GraphReader

Overrides:

readUndirected in class GraphReaderAdapter

Throws:

IOException - if any error occurs while reading the file

readUndirected

public Graph<Edge> readUndirected(File f,
                         Indexer<String> vertexIndexer)
                           throws IOException

Description copied from class: GraphReaderAdapter

Reads in the graph from the provided file, using the specified Indexer to decide how vertex labels in the file are mapped to numeric vertices.
