Class JsonSaver

java.lang.Object

io.improbable.keanu.util.io.JsonSaver

All Implemented Interfaces:

NetworkSaver

public class JsonSaver
extends java.lang.Object
implements NetworkSaver

A class for outputting a network to a JSON file. JSON output file contains information about the network (vertices, their types and connections), network state (values for constant and observed vertices, if saveValues parameter is set to true), as well as metadata (string key - value pairs, if metadata is passed in).

Usage: Create jsonSaver: JsonSaver jsonSaver = new JsonSaver(yourBayesianNetwork); or JsonSaver jsonSaver = new JsonSaver(yourBayesianNetwork, metadata); where metadata is a map between some keys and values in string format (for instance, "author": "Jane Doe"). To output network to a JSON file: jsonSaver.save(outputStream, saveValues);
