This was a bad design decision. Use of those calling conventions was deprecated in version 2.0, released in January 2012, and started to emit warnings. .PP All code to support those calling conventions has now been removed. .SH "COMPATIBILTY WITH libphonenumber" .IX Header "COMPATIBILTY WITH libphonenumber" libphonenumber is a similar project for other languages, maintained by Google. .PP If you pass in a country code for which no supporting module is available, the constructor will try to use a 'stub' class under Number::Phone::StubCountry::* that uses data automatically extracted from Google's libphonenumber project. libphonenumber doesn't have enough data to support all the features of Number::Phone. If you want to disable this, then pass 'nostubs' when you use the module: .PP .Vb 1 \& use Number::Phone qw(nostubs); .Ve .PP Alternatively, if you want to *always* use data derived from libphonenumber, you should use the Number::Phone::Lib module instead. This is a subclass of Number::Phone that will use the libphonenumber-derived stub classes even when extra data is available in, for example, Number::Phone::UK. You might want to do this for compatibility or performance. Number::Phone::UK is quite slow, because it uses a huge database for some of its features. .SH "METHODS" .IX Header "METHODS" All Number::Phone classes can implement the following object methods. .PP The implementations in the parent class all return undef unless otherwise noted. .PP Those methods whose names begin \f(CW\*(C`is_\*(C'\fR should return the following values: .IP "undef" 4 .IX Item "undef" The truth or falsehood can not be determined; .IP "0 (zero)" 4 .IX Item "0 (zero)" False \- eg, \fIis_personal()\fR might return 0 for a number that is assigned to a government department. .IP "1 (one)" 4 .IX Item "1 (one)" True .SS "IS_* methods" .IX Subsection "IS_* methods" .IP "is_valid" 4 .IX Item "is_valid" The number is valid within the national numbering scheme. It may or may not yet be allocated, or it may be reserved. Any number which returns true for any of the following methods will also be valid. .IP "is_allocated" 4 .IX Item "is_allocated" The number has been allocated to a telco for use. It may or may not yet be in use or may be reserved. .IP "is_in_use" 4 .IX Item "is_in_use" The number has been assigned to a customer or is in use by the telco for its own purposes. .IP "is_geographic" 4 .IX Item "is_geographic" The number refers to a geographic area. .IP "is_fixed_line" 4 .IX Item "is_fixed_line" The number, when in use, can only refer to a fixed line. .IP "is_mobile" 4 .IX Item "is_mobile" The number, when in use, can only refer to a mobile phone. .IP "is_pager" 4 .IX Item "is_pager" The number, when in use, can only refer to a pager. .IP "is_ipphone" 4 .IX Item "is_ipphone" The number, when in use, can only refer to a VoIP service. .IP "is_isdn" 4 .IX Item "is_isdn" The number, when in use, can only refer to an \s-1ISDN\s0 service. .IP "is_tollfree" 4 .IX Item "is_tollfree" Callers will not be charged for calls to this number under normal circumstances. .IP "is_specialrate" 4 .IX Item "is_specialrate" The number, when in use, attracts special rates. For instance, national dialling at local rates, or premium rates for services. .IP "is_adult" 4 .IX Item "is_adult" The number, when in use, goes to a service of an adult nature, such as porn. .IP "is_personal" 4 .IX Item "is_personal" The number, when in use, goes to an individual person. .IP "is_corporate" 4 .IX Item "is_corporate" The number, when in use, goes to a business. .IP "is_government" 4 .IX Item "is_government" The number, when in use, goes to a government department. Note that the emergency services are considered to be a network service so should *not* return true for this method. .IP "is_international" 4 .IX Item "is_international" The number is charged like a domestic number (including toll-free or special rate), but actually terminates in a different country. This covers the special dialling arrangements between Spain and Gibraltar, and between the Republic of Ireland and Northern Ireland, as well as services such as the various \*(L"Country Direct\*(R"\-a\-likes. See also the \f(CW\*(C`country()\*(C'\fR method. .IP "is_network_service" 4 .IX Item "is_network_service" The number is some kind of network service such as the operator, directory enquiries, emergency services etc .IP "is_drama" 4 .IX Item "is_drama" The number is for use in fiction, such as \s-1TV\s0 and Radio drama programmes. It will not be allocated for use in real life. .SS "\s-1OTHER NUMBER METADATA METHODS\s0" .IX Subsection "OTHER NUMBER METADATA METHODS" .IP "country_code" 4 .IX Item "country_code" The numeric code for this country. eg, 44 for the \s-1UK. \s0 Note that there is *no* + sign. .Sp While the superclass does indeed implement this (returning undef) this is nonsense in just about all cases, so you should always implement this. .IP "regulator" 4 .IX Item "regulator" Returns some text in an appropriate character set saying who the telecoms regulator is, with optional details such as their web site or phone number. .IP "areacode" 4 .IX Item "areacode" Return the area code \- if applicable \- for the number. If not applicable, the superclass implementation returns undef. .IP "areaname" 4 .IX Item "areaname" Return the name for the area code \- if applicable. If not applicable, the superclass definition returns undef. For instance, for a number beginning +44 20 it would return \&'London'. Note that this may return data in non-ASCII character sets. .IP "location" 4 .IX Item "location" This returns an approximate geographic location for the number if possible. Obviously this only applies to fixed lines! The data returned is, if defined, a reference to an array containing two elements, latitude and longitude, in degrees. North of the equator and East of Greenwich are positive. You may optionally return a third element indicating how confident you are of the location. Specify this as a number in kilometers indicating the radius of the error circle. .Sp The superclass implementation returns undef, which is a reasonable default. .IP "subscriber" 4 .IX Item "subscriber" Return the subscriber part of the number. .Sp While the superclass implementation returns undef, this is nonsense in just about all cases, so you should always implement this. .IP "operator" 4 .IX Item "operator" Return the name of the telco assigned this number, in an appropriate character set and with optional details such as their web site or phone number. Note that this should not take into account number portability. .Sp The superclass implementation returns undef, as this information is not easily available for most numbering plans. .IP "operator_ported" 4 .IX Item "operator_ported" Return the name of the telco to whom this number has been ported. If it is known to have not been ported, then return the same as \f(CW\*(C`operator()\*(C'\fR above. .Sp The superclass implementation returns undef, indicating that you don't know whether the number has been ported. .IP "type" 4 .IX Item "type" Return a listref of all the is_... methods above which are true. Note that this method should only be implemented in the super-class. eg, for the number +44 20 87712924 this might return \&\f(CW\*(C`[qw(valid allocated geographic)]\*(C'\fR. .IP "format" 4 .IX Item "format" Return a sanely formatted E.123\-compliant version of the number, complete with \&\s-1IDD\s0 code, eg for the \s-1UK\s0 number (0208) 771\-2924 it would return +44 20 8771 2924. .Sp The superclass implementation returns undef, which is nonsense, so you should always implement this. .IP "format_using" 4 .IX Item "format_using" If you want something different from E.123, then pass this the name of a formatter to use. .Sp For example, if you want to get \*(L"just the digits, ma'am\*(R", use the Raw formatter thus: .Sp .Vb 1 \& Number::Phone\->new(\*(Aq+44 20 8771 2924\*(Aq)\->format_using(\*(AqRaw\*(Aq); .Ve .Sp which will return: .Sp .Vb 1 \& 2087712924 .Ve .Sp It is a fatal error to specify a non-existent formatter. .IP "country" 4 .IX Item "country" The two letter \s-1ISO\s0 country code for the country in which the call will terminate. This is implemented in the superclass and you will only have to implement your own version for countries where part of the number range is overlayed with another country. .Sp Exception: for the \s-1UK,\s0 return 'uk', not 'gb'. .Sp Specifically, the superclass implementation looks at the class name and returns the last two-letter code it finds. eg ... .Sp .Vb 4 \& from Number::Phone::UK, it would return UK \& from Number::Phone::UK::IM, it would return IM \& from Number::Phone::NANP::US, it would return US \& from Number::Phone::FR::Full, it would return FR .Ve .IP "translates_to" 4 .IX Item "translates_to" If the number forwards to another number (such as a special rate number forwarding to a geographic number), or is part of a chunk of number-space mapped onto another chunk of number-space (such as where a country has a shortcut to (part of) another country's number-space, like how Gibraltar used to appear as an area code in Spain's numbering plan as well as having its own country code), then this method may return an object representing the target number. Otherwise it returns undef. .Sp The superclass implementation returns undef. .SS "\s-1HOW TO DIAL FROM ONE NUMBER TO ANOTHER\s0" .IX Subsection "HOW TO DIAL FROM ONE NUMBER TO ANOTHER" .IP "dial_to" 4 .IX Item "dial_to" Takes another Number::Phone object as its only argument and returns a string showing how to dial from the number represented by the invocant to that represented by the argument. .Sp Examples: .Sp .Vb 3 \& Call from +44 20 7210 3613 \& to +44 1932 341 111 \& You dial 01932341111 \& \& Call from +44 20 7210 3613 \& to +44 1932 341 111 \& You dial 01932341111 \& \& Call from +44 20 7210 3613 \& to +1 202 224 6361 \& You dial 0012022246361 \& \& Call from +1 202 224 6361 \& to +44 20 7210 3613 \& You dial 011442072103613 \& \& Call from +44 7979 866975 \& to +44 7979 866976 \& You dial 07979 866976 .Ve .Sp This method is implemented in the superclass, but you may have to define certain other methods to assist it. The algorithm is as follows: .RS 4 .IP "international call" 4 .IX Item "international call" Append together the source country's international dialling prefix (usually 00), then the destination country's code code, area code, and subscriber number. .IP "domestic call, different area code" 4 .IX Item "domestic call, different area code" Call the object's \f(CW\*(C`intra_country_dial_to()\*(C'\fR method. .Sp If it dies, return undef. .Sp If it returns anything other than undef, return that. .Sp If it returns undef, append together the country's out-of-area calling prefix (usually 0 or 1), the destination area code and subscriber number. .IP "domestic call, same area code" 4 .IX Item "domestic call, same area code" Call the object's \f(CW\*(C`intra_country_dial_to()\*(C'\fR method. .Sp If it dies, return undef. .Sp If it returns anything other than undef, return that. .Sp If it returns undef, return the destination subscriber number. .RE .RS 4 .RE .IP "intra_country_dial_to" 4 .IX Item "intra_country_dial_to" Takes an object (which should be in the same country as the invocant) and returns either undef (meaning \*(L"use the default behaviour\*(R") or a dialling string. If it dies this means \*(L"I don't know how to dial this number\*(R". .Sp The superclass implementation is to die. .Sp Note that the meaning of undef is a bit different for this method. .Sp Why die by default? Some countries have weird arrangements for dialling some numbers domestically. In fact, both the countries I'm most familiar with do, so I assume that others do too. .SS "\s-1CONSTRUCTOR\s0" .IX Subsection "CONSTRUCTOR" .IP "new" 4 .IX Item "new" Can be called with either one or two parameters. The *first* is an optional country code (see the \f(CW\*(C`country()\*(C'\fR method). The other is a phone number. If a country code is specified, and a subclass for that country is available, the phone number is passed to its constructor unchanged. .Sp If only one parameter is passed, then we try to figure out which is the right country subclass to use by pre-pending a + sign to the number if there isn't one, and looking the country up using Number::Phone::Country. That gives us a two letter country code that is used to try to load the right module. .Sp The constructor returns undef if it can not figure out what country you're talking about, or an object based on Google's libphonenumber data if there's no complete country-specific module available. .SH "SUBCLASSING" .IX Header "SUBCLASSING" Sub-classes should implement methods as above, including a \f(CW\*(C`new()\*(C'\fR constructor. The constructor should take a single parameter, a phone number, and should validate that. If the number is valid (use your \f(CW\*(C`is_valid()\*(C'\fR method!) then you can return a blessed object. Otherwise you should return undef. .PP The constructor *must* be capable of accepting a number with the + sign and the country's numeric code attached, but should also accept numbers in the preferred local format (eg 01234 567890 in the \s-1UK,\s0 which is the same number as +44 1234 567890) so that users can go straight to your class without going through Number::Phone's magic country detector. .PP Subclasses' names should be Number::Phone::XX, where \s-1XX\s0 is the two letter \&\s-1ISO\s0 code for the country, in upper case. So, for example, France would be \&\s-1FR\s0 and Ireland would be \s-1IE. \s0 As usual, the \s-1UK\s0 is an exception, using \s-1UK\s0 instead of the ISO-mandated \s-1GB. NANP\s0 countries are also an exception, going like Number::Phone::NANP::XX. .SH "UPDATES" .IX Header "UPDATES" Starting in March 2015 I intend to release updates approximately every three months, including new data from libphonenumber and \s-1OFCOM.\s0 .SH "BUGS/FEEDBACK" .IX Header "BUGS/FEEDBACK" Please report bugs by at , including, if possible, a test case. .SH "MAILING LIST" .IX Header "MAILING LIST" There is a mailing list for discussion and help. Please subscribe at . .PP Kindly hosted by Shadowcat . .SH "SEE ALSO" .IX Header "SEE ALSO" , a similar project for Java, \&\*(C+ and Javascript. Number::Phone imports its data. .SH "SOURCE CODE REPOSITORY" .IX Header "SOURCE CODE REPOSITORY" .SH "AUTHOR, COPYRIGHT and LICENCE" .IX Header "AUTHOR, COPYRIGHT and LICENCE" Copyright 2004 \- 2015 David Cantrell <\fIdavid@cantrell.org.uk\fR> .PP This software is free-as-in-speech software, and may be used, distributed, and modified under the terms of either the \s-1GNU\s0 General Public Licence version 2 or the Artistic Licence.
