.- Parameters:
graph
- the graph to write outw
- the writer instance to which the graph data will be written out- Throws:
java.io.IOException
- if writing the graph fails

setVertexIDs
public void setVertexIDs(com.google.common.base.Function<V,java.lang.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 oftoString
(and thus not guaranteed to be unique).- Parameters:
vertex_ids
- a mapping from vertex to ID
-
setEdgeIDs
public void setEdgeIDs(com.google.common.base.Function<E,java.lang.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
- a mapping from edge to ID
-
setGraphData
public void setGraphData(java.util.Map<java.lang.String,GraphMLMetadata<Hypergraph<V,E>>> graph_map)
Provides a map from data type name to graph data.- Parameters:
graph_map
- map from data type name to graph data
-
setVertexData
public void setVertexData(java.util.Map<java.lang.String,GraphMLMetadata<V>> vertex_map)
Provides a map from data type name to vertex data.- Parameters:
vertex_map
- map from data type name to vertex data
-
setEdgeData
public void setEdgeData(java.util.Map<java.lang.String,GraphMLMetadata<E>> edge_map)
Provides a map from data type name to edge data.- Parameters:
edge_map
- map from data type name to edge data
-
addGraphData

Adds a new graph data specification.- Parameters:
id
- the ID of the data to adddescription
- a description of the data to adddefault_value
- a default value for the data typegraph_transformer
- a mapping from graphs to their string representations
-
addVertexData
public void addVertexData(java.lang.String id, java.lang.String description, java.lang.String default_value, com.google.common.base.Function<V,java.lang.String> vertex_transformer)

- a default value for the data typevertex_transformer
- a mapping from vertices to their string representations
-
addEdgeData
public void addEdgeData(java.lang.String id, java.lang.String description, java.lang.String default_value, com.google.common.base.Function<E,java.lang.String> edge_transformer)
Adds a new edge data specification.- Parameters:
id
- the ID of the data to adddescription
