The code says:
public static class Path extends ArrayList<Statement>
There isn't support for reading/writing paths as an array of statements.
You could put the statements (loosing the order) into a model and write
that.
Or you can write your own code to print a path.
If you just want to see the path, use .toString (which might get a bit
long - in that case you need to write tyour own output format).

Hello friends,
I need to output the result of FindShortestPath(Model, start, end, filter)
to a file. I have already tried some methods. I got the result at a variable
Path pathOut = FSP.findShortestPath(...);
as I print the output, it is ok. I get the right triples
As I try to read it into an RDF file, I got no success:
I am trying this block :
caminho = AchaCaminhoMaisCurto.findShortestPath(m_model, m_a, m_g, ANY);
System.out.println("Shortest path: " +
(AchaCaminhoMaisCurto.findShortestPath(m_model, m_a, m_g, ANY)));
try {
PrintStream saida = new PrintStream ("file_path/saida9.rdf");
caminho.write(saida);
//saida.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Compiler says:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method write(PrintStream) is undefined for the type OntTools.Path
at ferramentas.Principal.main(Principal.java:169)
By the way: I have already tested to write the m_model, of course I got the
whole ontology. That is not what I need, I need only the classes in the
path.
Ok, It is all right, but which writing method should I use with OntTools?
