Class LedaGraphWriter

java.lang.Object

com.jgalgo.io.LedaGraphWriter

All Implemented Interfaces:

GraphWriter<Integer,Integer>

public final class LedaGraphWriter
extends Object

Write a graph in 'LEDA' format.

The LEDA format is a simple format for both directed and undirected graphs, used by the LEDA library. Vertices are numbered from 1 to n, and edges are numbered from 1 to m. It support a single weight for vertices and a single weight for edges. The weights can be any primitive, or a string.

By default, the writer will write the graph without any weights. Its possible to write one of the vertices weights and one of the edges weights in the format. Use the setVerticesWeightsKey(String) and setEdgesWeightsKey(String) methods to specify the keys of the weights to write.

Constructor Detail

LedaGraphWriter

public LedaGraphWriter()

Create a new writer.

Method Detail

setVerticesWeightsKey

public void setVerticesWeightsKey(String verticesWeightsKey)

Set the key of the vertices weights to write.

By default, the writer will write the graph without any weights. Use this method to specify the key of the vertices weights to write.

Parameters:

verticesWeightsKey - the key of the vertices weights to write, or null to write no vertices weights

See Also:

Graph.verticesWeights(String)

setEdgesWeightsKey

public void setEdgesWeightsKey(String edgesWeightsKey)

Set the key of the edges weights to write.

By default, the writer will write the graph without any weights. Use this method to specify the key of the edges weights to write.

Parameters:

edgesWeightsKey - the key of the edges weights to write, or null to write no edges weights

Graph.edgesWeights(String)

writeGraphImpl

public void writeGraphImpl(Graph<Integer,Integer> graph,
                           Writer writer)
                    throws IOException

Throws:

IOException

writeGraph

public final void writeGraph(Graph<V,E> graph,
                             Writer writer)

Description copied from interface: GraphWriter

Write a graph to an I/O writer.

Specified by:

writeGraph in interface GraphWriter<V,E>

Parameters:

graph - a graph

writer - an I/O writer to which the graph description will be written to
