Method Details

splitCommas

public static List<String> splitCommas(String string)

Splits a string on commas, removing quotation marks around entries.

Parameters:

string - a comma-seperated string, not null

Returns:

the entries

writeRoads

public static void writeRoads(File file,
 Graph<GeoLocation, RoadEdge> graph)
                       throws IOException

Writes the given roads graph to the specified file.

Parameters:

file - the file to write to, not null

graph - the graph to write, not null

Throws:

IOException - if an exception occurred writing

readRoads

public static Graph<GeoLocation, RoadEdge> readRoads(File file)
                                              throws IOException

Reads a road graph from the specified file.

Parameters:

file - the file, not null

Returns:

the road graph

Throws:

IOException - if an exception occurred reading

readRoads

public static Graph<GeoLocation, RoadEdge> readRoads(File file,
 BiConsumer<GeoLocation, GeoLocation> edgeConsumer)
                                              throws IOException

Reads a road graph from the specified file, with an optional consumer for edges.

Parameters:

file - the file, not null

edgeConsumer - a callback for the edges, can be null if not used

Returns:

the road graph

Throws:

IOException - if an exception occurred reading

readRoads

public static Graph<GeoLocation, RoadEdge> readRoads(File file,
 Predicate<GeoLocation> spatialFilter,
 BiConsumer<GeoLocation, GeoLocation> edgeConsumer)
                                              throws IOException

Reads a road graph from the specified file, with an optional consumer for edges and spatial filter.

Parameters:

file - the file, not null

spatialFilter - a filter for which points to load, can be null if not used

edgeConsumer - a callback for the edges, can be null if not used

Returns:

the road graph

Throws:

IOException - if an exception occurred reading

writeNetwork
