NAME

Business::Address::POBox - Check whether an address looks like a P.O.Box

SYNOPSIS

use Business::Address::POBox;

if (Business::Address::POBox->new->is_pobox($address)) {
    ...
}

DESCRIPTION

This class tries to determine whether or not an string refers to a P.O. box. This is sometims relevant if your business process, for legal reasons, needs a real address and not a P.O. box.

It has predefined blacklists and whitelists that should catch most english and german P.O. box addresses, but you can modify these lists with the methods provided. Note that the entries are literal strings, not regular expressions.

METHODS

new

my $obj = Business::Address::POBox->new;
my $obj = Business::Address::POBox->new(%args);

Creates and returns a new object. The constructor will accept as arguments a list of pairs, from component name to initial value. For each pair, the named component is initialized by calling the method of the same name with the given value. If called with a single hash reference, it is dereferenced and its key/value pairs are set as described before.

blacklist

my @values    = $obj->blacklist;
my $array_ref = $obj->blacklist;
$obj->blacklist(@values);
$obj->blacklist($array_ref);

Get or set the array values. If called without an arguments, it returns the array in list context, or a reference to the array in scalar context. If called with arguments, it expands array references found therein and sets the values.

blacklist_clear

$obj->blacklist_clear;

Deletes all elements from the array.

blacklist_count

my $count = $obj->blacklist_count;

Returns the number of elements in the array.

blacklist_index

my $element   = $obj->blacklist_index(3);
my @elements  = $obj->blacklist_index(@indices);
my $array_ref = $obj->blacklist_index(@indices);

Takes a list of indices and returns the elements indicated by those indices. If only one index is given, the corresponding array element is returned. If several indices are given, the result is returned as an array in list context or as an array reference in scalar context.

blacklist_pop

my $value = $obj->blacklist_pop;

Pops the last element off the array, returning it.

blacklist_push

$obj->blacklist_push(@values);

Pushes elements onto the end of the array.

blacklist_set

$obj->blacklist_set(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

blacklist_shift

my $value = $obj->blacklist_shift;

Shifts the first element off the array, returning it.

blacklist_splice

$obj->blacklist_splice(2, 1, $x, $y);
$obj->blacklist_splice(-1);
$obj->blacklist_splice(0, -1);

Takes three arguments: An offset, a length and a list.

Removes the elements designated by the offset and the length from the array, and replaces them with the elements of the list, if any. In list context, returns the elements removed from the array. In scalar context, returns the last element removed, or undef if no elements are removed. The array grows or shrinks as necessary. If the offset is negative then it starts that far from the end of the array. If the length is omitted, removes everything from the offset onward. If the length is negative, removes the elements from the offset onward except for -length elements at the end of the array. If both the offset and the length are omitted, removes everything. If the offset is past the end of the array, it issues a warning, and splices at the end of the array.

blacklist_unshift

$obj->blacklist_unshift(@values);

Unshifts elements onto the beginning of the array.

clear_blacklist

$obj->clear_blacklist;

Deletes all elements from the array.

clear_matcher

$obj->clear_matcher;

Deletes the object.

clear_whitelist

$obj->clear_whitelist;

Deletes all elements from the array.

count_blacklist

my $count = $obj->count_blacklist;

Returns the number of elements in the array.

count_whitelist

my $count = $obj->count_whitelist;

Returns the number of elements in the array.

index_blacklist

my $element   = $obj->index_blacklist(3);
my @elements  = $obj->index_blacklist(@indices);
my $array_ref = $obj->index_blacklist(@indices);

index_whitelist

my $element   = $obj->index_whitelist(3);
my @elements  = $obj->index_whitelist(@indices);
my $array_ref = $obj->index_whitelist(@indices);

matcher

my $object = $obj->matcher;
$obj->matcher($object);
$obj->matcher(@args);

If called with an argument object of type String::BlackWhiteList it sets the object; further arguments are discarded. If called with arguments but the first argument is not an object of type String::BlackWhiteList, a new object of type String::BlackWhiteList is constructed and the arguments are passed to the constructor.

If called without arguments, it returns the String::BlackWhiteList object stored in this slot; if there is no such object, a new String::BlackWhiteList object is constructed - no arguments are passed to the constructor in this case - and stored in the matcher slot before returning it.

matcher_clear

$obj->matcher_clear;

Deletes the object.

pop_blacklist

my $value = $obj->pop_blacklist;

Pops the last element off the array, returning it.

pop_whitelist

my $value = $obj->pop_whitelist;

Pops the last element off the array, returning it.

push_blacklist

$obj->push_blacklist(@values);

Pushes elements onto the end of the array.

push_whitelist

$obj->push_whitelist(@values);

Pushes elements onto the end of the array.

set_blacklist

$obj->set_blacklist(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

set_whitelist

$obj->set_whitelist(1 => $x, 5 => $y);

Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set.

shift_blacklist

my $value = $obj->shift_blacklist;

Shifts the first element off the array, returning it.

shift_whitelist

my $value = $obj->shift_whitelist;

Shifts the first element off the array, returning it.

splice_blacklist

$obj->splice_blacklist(2, 1, $x, $y);
$obj->splice_blacklist(-1);
$obj->splice_blacklist(0, -1);

Takes three arguments: An offset, a length and a list.

splice_whitelist

$obj->splice_whitelist(2, 1, $x, $y);
$obj->splice_whitelist(-1);
$obj->splice_whitelist(0, -1);

Takes three arguments: An offset, a length and a list.

unshift_blacklist

$obj->unshift_blacklist(@values);

Unshifts elements onto the beginning of the array.

unshift_whitelist

$obj->unshift_whitelist(@values);

Takes three arguments: An offset, a length and a list.

whitelist_unshift

$obj->whitelist_unshift(@values);

update

Call this method when you've changed the whitelist() or the blacklist() so the matcher knows about the changes.

is_pobox

This is the central method of this class. It takes a string argument and checks it against the whitelist and the blacklist. Returns a boolean value - true if the string passes the whitelist or is at least not caught by the blacklist, false if the string is caught by the blacklist.
