read2Files[TLabel](lFile: String, eFile: String, inverse: Boolean = false)(implicit arg0: ClassTag[TLabel]): MGraph[TLabel]
Read a graph from TWO files: 'lFile' is a file with one label per line, where each line represents the vertex with id <lineNumber>.
Read a graph from TWO files: 'lFile' is a file with one label per line, where each line represents the vertex with id <lineNumber>. 'eFile' is a file with each line representing the vertex with id <lineNumber>, and each line contains a space-separated list of vertices to which the current vertex is adjacent.
- lFile
the file containing the graph labels
- eFile
the file the edges (to create adjacency sets)
- inverse
whether to store inverse adjacency sets (parents)
