                    ZoneId timeZone)

Method Detail

read

public static Set<WikidataCity> read(InputStream is)

Parameters:

is - stream to read from

Returns:

set without duplicates

from

public static WikidataCity from(org.apache.commons.csv.CSVRecord rec)
                         throws MalformedURLException

Parameters:

rec - data to build a city object

Returns:

a City object, if the data in rec was ok

Throws:

RuntimeException - when something goes wrong to easily ignore the dataset.

MalformedURLException

byId

public static Optional<WikidataCity> byId(Collection<WikidataCity> set,
                                          String id)
