Class MapServer

java.lang.Object

MapServer

public class MapServer
extends java.lang.Object

This MapServer class is the entry point for running the JavaSpark web server for the BearMaps application project, receiving API calls, handling the API call processing, and generating requested images and routes. You should not need to modify this file unless you're doing the Autocomplete part of the project, though you are welcome to do so. This code is using BearMaps skeleton code version 2.0.

Method Detail

initialize

public static void initialize()

Place any initialization statements that will be run before the server main loop here. Do not place it in the main function. Do not place initialization code anywhere else. This is for testing purposes, and you may fail tests otherwise.

main

public static void main(java.lang.String[] args)

clearRoute

public static void clearRoute()

Clear the current found route, if it exists.

getLocationsByPrefix

public static java.util.List<java.lang.String> getLocationsByPrefix(java.lang.String prefix)

In linear time, collect all the names of OSM locations that prefix-match the query string.

Parameters:

prefix - Prefix string to be searched for. Could be any case, with our without punctuation.

Returns:

A List of the full names of locations whose cleaned name matches the cleaned prefix.

getLocations

public static java.util.List<java.util.Map<java.lang.String,java.lang.Object>> getLocations(java.lang.String locationName)

Collect all locations that match a cleaned locationName, and return information about each node that matches.

Parameters:

locationName - A full name of a location searched for.

Returns:

A list of locations whose cleaned name matches the cleaned locationName, and each location is a map of parameters for the Json response as specified:
"lat" : Number, The latitude of the node.
"lon" : Number, The longitude of the node.
"name" : String, The actual name of the node.
"id" : Number, The id of the node.
