Class GraphMLWriter<V,E>

java.lang.Object
  edu.uci.ics.jung.io.GraphMLWriter<V,E>

public class GraphMLWriter<V,E>
extends Object

Writes graphs out in GraphML format. Current known issues:

• Only supports one graph per output file.
• Does not indent lines for text-format readability.

          throws IOException

Parameters:

graph -

w -

Throws:

                        String value,
                        String contents)

setVertexIDs

public void setVertexIDs(org.apache.commons.collections15.Transformer<V,String> vertex_ids)

Provides an ID that will be used to identify a vertex in the output file. If the vertex IDs are not set, the ID for each vertex will default to the output of toString (and thus not guaranteed to be unique).

Parameters:

vertex_ids -

setEdgeIDs

public void setEdgeIDs(org.apache.commons.collections15.Transformer<E,String> edge_ids)

Provides an ID that will be used to identify an edge in the output file. If any edge ID is missing, no ID will be written out for the corresponding edge.

Parameters:

edge_ids -

setGraphData

public void setGraphData(Map<String,GraphMLMetadata<Hypergraph<V,E>>> graph_map)

Provides a map from data type name to graph data.

setVertexData

public void setVertexData(Map<String,GraphMLMetadata<V>> vertex_map)

Provides a map from data type name to vertex data.

setEdgeData

public void setEdgeData(Map<String,GraphMLMetadata<E>> edge_map)

Provides a map from data type name to edge data.

addGraphData

public void addGraphData(String id,
                         String description,
                         String default_value,
                         org.apache.commons.collections15.Transformer<Hypergraph<V,E>,String> graph_transformer)

Adds a new graph data specification.

addVertexData

public void addVertexData(String id,
                          String description,
                          String default_value,
                          org.apache.commons.collections15.Transformer<V,String> vertex_transformer)

Adds a new vertex data specification.

addEdgeData

public void addEdgeData(String id,
                        String description,
                        String default_value,
                        org.apache.commons.collections15.Transformer<E,String> edge_transformer)

Adds a new edge data specification.

setVertexDescriptions

public void setVertexDescriptions(org.apache.commons.collections15.Transformer<V,String> vertex_desc)

Provides vertex descriptions.

setEdgeDescriptions

public void setEdgeDescriptions(org.apache.commons.collections15.Transformer<E,String> edge_desc)
