      public boolean write​(Graph<java.lang.Long> graph, java.lang.String file)
      Description copied from interface: GraphWriter
      Writes a graph into a file. It writes the weights, but not the types
      Specified by:
      write in interface GraphWriter<java.lang.Long>
      Parameters:
      graph - The graph we want to write.
      file - The file.
      Returns:
      true if everything went OK, false otherwise.
