Package com.gengoai.graph.io

Interface GraphWriter<V>

Type Parameters:

V - the vertex type

All Known Implementing Classes:

GraphJson, GraphViz

public interface GraphWriter<V>

Common interface for writing graphs from resources.

The vertices of the graph are first converted into an intermediate representation (Vertex), which defines a label and set of properties. Edges are translated into a property map.

Method Summary

Modifier and Type	Method	Description
void	setEdgeEncoder(EdgeEncoder<V> encoder)	Sets the edge encoder.
void	setVertexEncoder(VertexEncoder<V> encoder)	Sets the vertex encoder
default void	write(Graph<V> graph, Resource location)	Writes the given graph to the give location in this format, using the defined vertex and edge encoders.
void	write(Graph<V> graph, Resource location, Multimap<String,String> parameters)	Writes the given graph to the give location in this format, using the defined vertex and edge encoders.

Method Detail

setVertexEncoder

void setVertexEncoder(VertexEncoder<V> encoder)

Parameters:

encoder - the encoder

setEdgeEncoder

void setEdgeEncoder(EdgeEncoder<V> encoder)

Sets the edge encoder.

Parameters:

encoder - the encoder

write

default void write(Graph<V> graph,
                   Resource location)
            throws IOException

Parameters:

graph - the graph to write

location - the location to write to

Throws:

IOException - Something went wrong writing the graph

write

void write(Graph<V> graph,
           Resource location,
           Multimap<String,String> parameters)
    throws IOException
