* ## Usage ## * * The basic API for this class is the same for every database. First, you * create a reader object, specifying a file name. You then call the method * corresponding to the specific database, passing it the IP address you want * to look up. * * If the request succeeds, the method call will return a model class for * the method you called. This model in turn contains multiple record classes, * each of which represents part of the data returned by the database. If * the database does not contain the requested information, the attributes * on the record class will have a `null` value. * * If the address is not in the database, an * {@link \GeoIp2\Exception\AddressNotFoundException} exception will be * thrown. If an invalid IP address is passed to one of the methods, a * SPL {@link \InvalidArgumentException} will be thrown. If the database is * corrupt or invalid, a {@link \MaxMind\Db\Reader\InvalidDatabaseException} * will be thrown. */ class Reader implements ProviderInterface {
