Class PajekNetWriter<V,E>

java.lang.Object

edu.uci.ics.jung.io.PajekNetWriter<V,E>

public class PajekNetWriter<V,E>
extends Object

Writes graphs in the Pajek NET format.

Labels for vertices, edge weights, and vertex locations may each optionally be specified. Note that vertex location coordinates must be normalized to the interval [0, 1] on each axis in order to conform to the Pajek specification.

Method Detail

save

public void save(Graph<V,E> g,
                 String filename,
                 com.google.common.base.Function<V,String> vs,
                 com.google.common.base.Function<E,Number> nev,
                 com.google.common.base.Function<V,Point2D> vld)
          throws IOException

Saves the graph to the specified file.

Parameters:

g - the graph to be saved

filename - the filename of the file to write the graph to

vs - mapping from vertices to labels

nev - mapping from edges to weights

vld - mapping from vertices to locations

Throws:

IOException - if the graph cannot be saved

save

public void save(Graph<V,E> g,
                 String filename,
                 com.google.common.base.Function<V,String> vs,
                 com.google.common.base.Function<E,Number> nev)
          throws IOException

Saves the graph to the specified file.

Parameters:

g - the graph to be saved

filename - the filename of the file to write the graph to

vs - mapping from vertices to labels

nev - mapping from edges to weights

Throws:

IOException - if the graph cannot be saved

save

public void save(Graph<V,E> g,
                 String filename)
          throws IOException

Saves the graph to the specified file. No vertex labels are written, and the edge weights are written as 1.0.

Parameters:

g - the graph to be saved

filename - the filename of the file to write the graph to

Throws:

IOException - if the graph cannot be saved

save

public void save(Graph<V,E> g,
                 Writer w)
          throws IOException

Saves the graph to the specified writer. No vertex labels are written, and the edge weights are written as 1.0.

Parameters:

g - the graph to be saved

w - the writer instance to write the graph to

Throws:

IOException - if the graph cannot be saved

save

public void save(Graph<V,E> g,
                 Writer w,
                 com.google.common.base.Function<V,String> vs,
                 com.google.common.base.Function<E,Number> nev)
          throws IOException

Saves the graph to the specified writer.

Parameters:

g - the graph to be saved

w - the writer instance to write the graph to

vs - mapping from vertices to labels

nev - mapping from edges to weights

Throws:

IOException - if the graph cannot be saved

save

public void save(Graph<V,E> graph,
                 Writer w,
                 com.google.common.base.Function<V,String> vs,
                 com.google.common.base.Function<E,Number> nev,
                 com.google.common.base.Function<V,Point2D> vld)
          throws IOException

Saves the graph to the specified writer.

Parameters:

graph - the graph to be saved

w - the writer instance to write the graph to

vs - mapping from vertices to labels (no labels are written if null)

nev - mapping from edges to weights (defaults to weights of 1.0 if null)

vld - mapping from vertices to locations (no locations are written if null)

Throws:

IOException - if the graph cannot be saved
