=head1 METHODS

=head2 details()

It returns an object of type L on success. The only
parameter requires is the post code.

    use strict; use warnings;
    use Address::PostCode::UK;

    my $address   = Address::PostCode::UK->new;
    my $post_code = 'Post Code';
    my $place     = $address->details($post_code);

    print "Latitude : ", $place->geo->lat, "\n";
    print "Longitude: ", $place->geo->lng, "\n";

=cut

sub details {
    my ($self, $post_code) = @_;

    die "ERROR: Missing required param 'post code'.\n" unless defined $post_code;
    die "ERROR: Invalid format for UK post code [$post_code].\n" unless ($post_code =~ /[A-Z]{1,2}[0-9][0-9A-Z]?\s?[0-9][A-Z]{2}/gi);

    $post_code =~ s/\s//g;
    my $url      = sprintf("%s/postcode/%s.json", $BASE_URL, $post_code);
    my $response = $self->get($url);
    my $contents = from_json($response->{'content'});

    my ($geo, $ward, $council, $constituency);
    $geo  = Address::PostCode::UK::Place::Geo->new($contents->{'geo'})
        if (exists $contents->{'geo'});
    $ward = Address::PostCode::UK::Place::Ward->new($contents->{'administrative'}->{'ward'})
        if (exists $contents->{'administrative'}->{'ward'});
    $council = Address::PostCode::UK::Place::Council->new($contents->{'administrative'}->{'council'})
        if (exists $contents->{'administrative'}->{'council'});
    $constituency = Address::PostCode::UK::Place::Constituency->new($contents->{'administrative'}->{'constituency'})
        if (exists $contents->{'administrative'}->{'constituency'});

    return Address::PostCode::UK::Place->new(
        'geo' => $geo, 'ward' => $ward, 'council' => $council, 'constituency' => $constituency);
}

=head2 nearest()

It returns ref to a list of objects of type L on
success. The required parameters are the post code and distance in miles.

    use strict; use warnings;
    use Address::PostCode::UK;

    my $address   = Address::PostCode::UK->new;
    my $post_code = 'Post Code';
    my $distance  = 1;
    my $locations = $address->nearest($post_code, $distance);

    print "Location Latitude : ", $locations->[0]->lat, "\n";
    print "Location Longitude: ", $locations->[0]->lng, "\n";

=cut

sub nearest {
    my ($self, $post_code, $distance) = @_;

    die "ERROR: Missing required param 'post code'.\n" unless defined $post_code;
    die "ERROR: Missing required param 'distance'.\n"  unless defined $distance;

    die "ERROR: Invalid format for UK post code [$post_code].\n" unless ($post_code =~ /[A-Z]{1,2}[0-9][0-9A-Z]?\s?[0-9][A-Z]{2}/gi);
    die "ERROR: Invalid distance [$distance].\n" unless ($distance =~ /^[\d+]$/);

    $post_code =~ s/\s//g;
    my $url      = sprintf("%s/postcode/nearest?postcode=%s&miles=%d&format=json", $BASE_URL, $post_code, $distance);
    my $response = $self->get($url);
    my $contents = from_json($response->{'content'});

    my $locations = [];
    foreach (@$contents) {
        push @$locations, Address::PostCode::UK::Location->new($_);
    }
