apply(name: String, base: String = BASE_DIR, ext: String = EXT, sep: Char = ','): Graph
Read a graph from a file based on the format used by 'print' and 'write':
Read a graph from a file based on the format used by 'print' and 'write':
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
- sep
the character separating the values (e.g., ',', ' ', '\t')
-
def
makeSet(eStrArr: Array[String]): Set[Int]
Given an array of integers as strings, make the corresponding set.

def
read2Files(lFile: String, eFile: String, inverse: Boolean = false): Graph
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)

def
read2PajekFile(lFile: String, eFile: String, inverse: Boolean = false): Graph
Read a graph from TWO specially formatted Pajek files.
Read a graph from TWO specially formatted Pajek files.
- lFile
the file containing the graph labels
- eFile
the file the edges (to create adjacency sets)
- inverse
whether to store inverse adjacency sets (parents)
