NAME

PerlBean::Attribute::Factory - factory package to generate PerlBean::Attribute objects

SYNOPSIS

use strict;
use PerlBean::Attribute::Factory;
my $factory = PerlBean::Attribute::Factory->new ();
my $attr = $factory->createAttribute ({
	type => 'BOOLEAN',
	attribute_name => 'true',
	short_description => 'something is true',
});

use IO::File;
-d 'tmp' || mkdir ('tmp');
my $fh = IO::File->new ('> tmp/PerlBean_Attribute_Factory.pl.out');
$attr->writeMethods ($fh);
$attr->writeDocMethods ($fh);

ABSTRACT

PerlBean::Attribute object factory

DESCRIPTION

PerlBean::Attribute::Factory objects create instances of PerlBean::Attribute objects.

CONSTRUCTOR

new ()

Creates a new PerlBean::Attribute::Factory object.

METHODS

createAttribute (OPT_HASH_REF)

Returns PerlBean::Attribute objects based on OPT_HASH_REF. OPT_HASH_REF is a hash reference used to pass initialization options. The selected subclass of PerlBean::Attribute is initialized using OPT_HASH_REF. On error an exception Error::Simple is thrown.

Options for OPT_HASH_REF used by this method may include:

associative

Boolean flag. States that the returned attribute must be unique, associative MULTI. Defaults to 0. Only makes sense if type is MULTI and unique is true.

method_key

Boolean flag. States that the returned attribute must be unique, associative MULTI. Defaults to 0. Only makes sense if type is MULTI and unique is true.

ordered

Boolean flag. States that the returned attribute must be an ordered list. Defaults to 0. Only makes sense if type is MULTI.

type

If type is BOOLEAN a PerlBean::Attribute::Boolean, on SINGLE a PerlBean::Attribute::Single and on MULTI a PerlBean::Attribute::Multi is returned. Defaults to SINGLE. NOTE: type has precedence over ordered and unique.

unique

Boolean flag. States that the items in the MULTI attribute must be unique. Defaults to 0. Only makes sense if type is MULTI.

Options for OPT_HASH_REF passed to package PerlBean::Attribute may include:

attribute_name

Passed to "setAttributeName ()". Mandatory option.

default_value

Passed to "setDefaultValue ()".

exception_class

Passed to "setExceptionClass ()". Defaults to Error::Simple.

mandatory

Passed to "setMandatory ()". Defaults to 0.

method_base

Passed to "setMethodBase ()".

perl_bean

Passed to "setPerlBean ()".

short_description

Passed to "setShortDescription ()".

Options for OPT_HASH_REF passed to package PerlBean::Attribute::Single may include:

allow_empty

Passed to "setAllowEmpty ()". Defaults to 1.

allow_isa

Passed to "setAllowIsa ()". Must be an ARRAY reference.

allow_ref

Passed to "setAllowRef ()". Must be an ARRAY reference.

allow_rx

Passed to "setAllowRx ()". Must be an ARRAY reference.

allow_value

Passed to "setAllowValue ()". Must be an ARRAY reference.
