Package jline.io

Class LDESResultIO

java.lang.Object

jline.io.LDESResultIO

public class LDESResultIO
extends Object

Provides save/load functionality for LDES solver results to/from JSON format.

Serializes LDESResult (and base SolverResult) fields to a JSON file that can be parsed by the Python wrapper or other tools without needing JVM access.

Usage:

   // Save result
   LDESResultIO.save(result, sn, "result.json");

   // Load result
   LDESResult result = LDESResultIO.load("result.json");

Method Details

save

public static void save(LDESResult result,
 NetworkStruct sn,
 String filename)
                 throws IOException

Saves an LDESResult and associated NetworkStruct to a JSON file.

Parameters:

result - the LDES solver result

sn - the network structure (for station/class names)

filename - the output file path

Throws:

IOException - if the file cannot be written

save

public static void save(LDESResult result,
 NetworkStruct sn,
 String filename,
 boolean trajectory)
                 throws IOException

Saves an LDESResult and associated NetworkStruct to a JSON file.

Parameters:

result - the LDES solver result

sn - the network structure (for station/class names)

filename - the output file path

trajectory - if true, include transient trajectory data (QNt, UNt, TNt, t)

Throws:

IOException - if the file cannot be written

load

public static LDESResult load(String filename)
                       throws IOException

Loads an LDESResult from a JSON file.

Parameters:

filename - the input file path

Returns:

the deserialized LDESResult

Throws:

IOException - if the file cannot be read or the format is invalid

loadStationNames

public static List<String> loadStationNames(String filename)
                                     throws IOException

Parameters:

filename - the result JSON file path

Returns:

list of class names

Throws:

IOException - if the file cannot be read
