Class GmlImporter<V,E>

java.lang.Object

org.jgrapht.ext.GmlImporter<V,E>

Type Parameters:

V - the vertex type

E - the edge type

All Implemented Interfaces:

GraphImporter<V,E>

Deprecated.

Use GmlImporter instead.

@Deprecated
public class GmlImporter<V,E>
extends Object
implements GraphImporter<V,E>

Imports a graph from a GML file (Graph Modeling Language).

For a description of the format see http://www. infosun.fmi.uni-passau.de/Graphlet/GML/.

Below is small example of a graph in GML format.

 graph [
   node [ 
     id 1
   ]
   node [
     id 2
   ]
   node [
     id 3
   ]
   edge [
     source 1
     target 2 
     weight 2.0
   ]
   edge [
     source 2
     target 3
     weight 3.0
   ]
 ]
 

In case the graph is an instance of WeightedGraph then the importer also reads edge weights. Otherwise edge weights are ignored.

Constructor Detail

GmlImporter

public GmlImporter(VertexProvider<V> vertexProvider,
                   EdgeProvider<V,E> edgeProvider)

Deprecated.

Constructs a new importer.

Parameters:

vertexProvider - provider for the generation of vertices. Must not be null.

edgeProvider - provider for the generation of edges. Must not be null.

Method Detail

getVertexProvider

public VertexProvider<V> getVertexProvider()

Deprecated.

Get the vertex provider

Returns:

the vertex provider

setVertexProvider

public void setVertexProvider(VertexProvider<V> vertexProvider)

Deprecated.

Set the vertex provider

Parameters:

vertexProvider - the new vertex provider. Must not be null.

getEdgeProvider

public EdgeProvider<V,E> getEdgeProvider()

Deprecated.

Get the edge provider

Returns:

The edge provider

setEdgeProvider

public void setEdgeProvider(EdgeProvider<V,E> edgeProvider)

Deprecated.

Set the edge provider.

Parameters:

edgeProvider - the new edge provider. Must not be null.

importGraph

public void importGraph(Graph<V,E> graph,
                        Reader input)
                 throws ImportException

Deprecated.

Import a graph.

The provided graph must be able to support the features of the graph that is read. For example if the gml file contains self-loops then the graph provided must also support self-loops. The same for multiple edges.

If the provided graph is a weighted graph, the importer also reads edge weights. Otherwise edge weights are ignored.

Specified by:

importGraph in interface GraphImporter<V,E>

Parameters:

graph - the output graph

input - the input reader

Throws:

ImportException - in case an error occurs, such as I/O or parse error
