  20. def write(name: String = g.name, base: String = BASE_DIR, ext: String = EXT): Unit

    Write graph 'g' to a file in the following format:

    Write graph 'g' to a file in the following format:

    Graph (<name>, <inverse> <nVertices> <vertexId>

    name

    the file-name containing the graph's vertex, edge and label information

    base

    the base sub-directory for storing graphs

    ext

    the standard file extension for graph

  21. def write2IgraphFiles(prefix: String): (String, String)

    Write the graph to TWO 'igraph' compatible files.

    Write the graph to TWO 'igraph' compatible files.

  22. def write2Neo4JFiles(lFile: String, eFile: String): Unit

    Write the graph to TWO 'Neo4J' compatible files: 'lFile' and 'eFile' so that they may be fed into 'Neo4j' with one of its utilities.

    Write the graph to TWO 'Neo4J' compatible files: 'lFile' and 'eFile' so that they may be fed into 'Neo4j' with one of its utilities. FIX: need to handle multiple edge types.

    lFile

    the file containing the graph labels (line: vertex-id TAB label)

    eFile

    the file the edges (line: start-id TAB end-id TAB type)
