NAME

SeeAlso::Identifier::Factory - Identify and create identifiers

VERSION

version 0.71

SYNOPSIS

$identifier = $factory->create( $could_be_an_identifier_string );

DESCRIPTION

A SeeAlso::Identifier::Factory object is given a string (via its method create) and returns a well-defined SeeAlso::Identifier object. A factory is useful to parse a string that may be an identifier of several identifier kinds.

The factory knows a list of identifier types (subclasses of SeeAlso::Identifier); the first type that successfully parses the provided string value is used to create the identifier object. If no type works, an empty identifier of the first type is returned.

METHODS

new ( %params )

Create a new Identifier Factory. You can either pass an array reference with identifier class name or a hash of methods that will be used to create a new identifier class:

$factory = new SeeAlso::Identifier::Factory
    type => [qw( class1 class2 ... )]

$factory = new SeeAlso::Identifier::Factory
    parse => sub { ... },
    canonical => sub { lc($_[0]) },
    hash => sub { md5_hex($_[0]) },
    type => '...';

create ( $value )

Create a new SeeAlso::Identifier object as described above.

FUNCTIONS

makeclass

Dynamically creates a subclass of SeeAlso::Identifier with given name and methods.
