Detailed Description

Parses OSM raw output from the Overpass Turbo API and initializes a graph representation of the data. It supports handling nodes and ways to construct vertices and edges in the graph.

Constructor & Destructor Documentation

OsmParser()

ch.routify.osmparser.OsmParser.OsmParser ( String pathOfSourceFile ) throws FileNotFoundException, ParseException

inline

Constructs an OsmParser and loads data from a specified source file.

Parameters

pathOfSourceFile

Path to the GeoJSON file containing OSM data.

Exceptions

FileNotFoundException	If the source file is not found.
ParseException	If parsing the JSON data fails.

Member Function Documentation

clear()

void ch.routify.osmparser.OsmParser.clear ( )

inline

Clears internal data structures to release memory.

exportOsmIdToCoordinates()

void ch.routify.osmparser.OsmParser.exportOsmIdToCoordinates ( String path )

inline

Exports a mapping of OSM IDs to their corresponding latitude and longitude coordinates to a specified file. The method iterates over a collection of nodes, each represented as a JSONObject, extracting the OSM ID, latitude, and longitude. These details are then formatted and written to a file in a JSON structure.

Parameters

path	The file system path where the exported JSON file will be saved. It specifies the location and name of the file. The method assumes that the path is valid and that it has the necessary permissions to write to it.

Exceptions

IOException

If an I/O error occurs during writing to the file. This includes cases where the file cannot be opened for writing, if there is an error during writing to the file, or if the file cannot be closed.

getNodes()

JSONArray ch.routify.osmparser.OsmParser.getNodes ( )

inline

getWays()

JSONArray ch.routify.osmparser.OsmParser.getWays ( )

inline

initializeGraph()

void ch.routify.osmparser.OsmParser.initializeGraph ( CustomGraph< CustomVertex, CustomEdge > graph )

inline

Initializes the graph with vertices and edges based on the parsed OSM data.

Parameters

graph

The graph to be initialized.

main()

static void ch.routify.osmparser.OsmParser.main ( String[] args ) throws FileNotFoundException, ParseException, IOException

inlinestatic

Main method to demonstrate the usage of OsmParser.

Parameters

args	Command line arguments (not used).

Exceptions

FileNotFoundException	If the source file is not found.
ParseException	If parsing the JSON data fails.
IOException	If an I/O error occurs.
