# DESCRIPTION

This module calculates the shipping costs for the Dutch PostNL, based on country, and weight etc.

The shipping cost information is based on 'Posttarieven Per januari 2014'.

It returns the shipping costs in euro or undef (which usually means the parcel is heavier than the maximum allowed weight; check `\$Business::PostNL::ERROR`).

## METHODS

The following methods can be used

### new

`new` creates a new `Business::PostNL` object. No more, no less.

### country

Sets the country (ISO 3166, 2-letter country code) and returns the zone number used by PostNL (or 0 for The Netherlands (NL)).

This value is mandatory for the calculations.

Note that the reserved IC has been used for the Canary Islands. This has not been adopted by ISO 3166 yet. The Channel Islands are completely ignored due to a lack of a code.

### calculate

Method to calculate the actual shipping cost based on the input (see methods above). These options can also be passed straight in to this method (see SYNOPSIS).

Two settings are mandatory: country and weight. The rest are given a default value that will be used unless told otherwise.

Returns the shipping costs in euro, or undef (see \$Business::PostNL::ERROR in that case).

### _generate_path

Internal method to create the path to walk through the pricing table. Don't call this, use calculate instead.

### _pointer_to_element

Blame merlyn for this internal method. It's using List::Util to "grep" the information needed.

Don't call this, use calculate instead.

### weight

Sets and/or returns the weight of the parcel in question in grams.

This value is mandatory for the calculations.

### large

Sets and/or returns the value of this option. Defaults to undef (meaning: the package will fit through the mail slot).

### priority [DEPRECATED]

PostNL still requires you to put a priority sticker on your letters and parcels, but this seems to be solely for speed of delivery. I couldn't find any price difference, hence this setting is ignored from now on and only here for backwards compatability.

### tracktrace

Sets and/or returns the value of this options. Defaults to undef (meaning: no track & trace feature wanted). When a parcel destined for abroad weighs over 2 kilograms, default is 1, while over 2kg it's not even optional anymore.

### register

Sets and/or returns the value of this options. Defaults to undef (meaning: parcel is not registered (Dutch: aangetekend)).

### receipt [DEPRECATED]

No longer an option, solely here for backwards compatibility.

### machine

Sets and/or returns the value of this options. Defaults to undef (meaning: stamps will be used, not the machine (Dutch: frankeermachine)).

Only interesting for destinies within NL. Note that "Pakketzegel AVP" and "Easystamp" should also use this option.

# CAVEAT

The Dutch postal agency (PostNL) uses many, many, many various ways for you to ship your parcels. Some of them are included in this module, but a lot of them not (maybe in the future? Feel free to patch ;-)
