 use Bric::Biz::ATType;

This class sets up properties that are common to all elements (Bric::Biz::AssetType) objects of a type.

$obj = Bric::Biz::ATType->new($init);

Constructs and returns a new Bric::Biz::ATType object initialized with the parameters in the CW$init hash reference. The supported keys for CW$init are:

name

The name of this ATType.

description

A short description of this ATType.

top_level

A boolean value flagging whether elements (AssetTypes) of this this ATType represent top level elements (story type elements or media type elements) or subelements. Defaults to false.

paginated

A boolean value flagging whether elements (AssetTypes) of this this ATType represent pages. Defaults to false.

fixed_url

A boolean value flagging whether elements (AssetTypes) of this this ATType are fixed URL elements. Defaults to false.

related_story

A boolean value flagging whether elements (AssetTypes) of this this ATType are rleated story elements. Defaults to false.

related_media

A boolean value flagging whether elements (AssetTypes) of this this ATType are rleated media elements. Defaults to false.

media

A boolean value flagging whether elements (AssetTypes) of this this ATType are media elements. Defaults to false.

biz_class_id

The ID corresponding to the Bric::Util::Class entry for one of the following classes:

Bric::Biz::Asset::Busines::Story

Bric::Biz::Asset::Busines::Media

Bric::Biz::Asset::Busines::Media::Image

Bric::Biz::Asset::Busines::Media::Audio

Bric::Biz::Asset::Busines::Media::Video

Throws: NONE. Side Effects: NONE. Notes: NONE. Looks up and instantiates a new Bric::Biz::ATType object based on the Bric::Biz::ATType object ID or name passed. If CW$id or CW$name is not found in the database, CWlookup() returns CWundef. Throws:

*

Too many Bric::Biz::ATType objects found.

*

Unable to connect to database.

*

Unable to prepare SQL statement.

*

Unable to select column into arrayref.

*

Unable to execute SQL statement.

*

Unable to bind to columns to statement handle.

*

Unable to fetch row from statement handle. Side Effects: NONE. Notes: NONE. Returns a list or anonymous array of Bric::Biz::ATType objects based on the search parameters passed via an anonymous hash. The supported lookup keys are:

name

Lookup ATType by name.

name

Lookup ATType by description.

top_level

Boolean; return all top level ATTypes

paginated

Boolean; return all paginated ATTypes.

fixed_url

Boolean; return all fixed URL ATTypes.

active

Boolean; return all active ATTypes. If passed as all, returns all ATTypes.

related_story

Boolean; return all related story ATTypes.

related_media

Boolean; return all related media ATTypes.

media

Boolean; return all media ATTypes.

biz_class_id

Return all ATTypes associated with this business class ID. See CWnew() for a list of business asset classes.

grp_id

Return all ATTypes in the Bric::Util::Grp::ElementType group corresponding to this ID. Throws:

*

Unable to connect to database.

*

Unable to prepare SQL statement.

*

Unable to select column into arrayref.

*

Unable to execute SQL statement.

*

Unable to bind to columns to statement handle.

*

Unable to fetch row from statement handle. Side Effects: NONE. Notes: NONE.

$st->DESTROY

Dummy method to prevent wasting time trying to AUTOLOAD DESTROY. Throws: NONE. Side Effects: NONE. Notes: NONE.

Returns a list or anonymous array of Bric::Biz::ATType object IDs based on the search criteria passed via an anonymous hash. The supported lookup keys are the same as those for CWlist(). Throws:

*

Unable to connect to database.

*

Unable to prepare SQL statement.

*

Unable to select column into arrayref.

*

Unable to execute SQL statement.

*

Unable to bind to columns to statement handle.

*

Unable to fetch row from statement handle. Side Effects: NONE. Notes: NONE. Returns an anonymous hash of introspection data for this object. If called with a true argument, it will return an ordered list or anonymous array of introspection data. If a second true argument is passed instead of a first, then a list or anonymous array of introspection data will be returned for properties that uniquely identify an object (excluding CWid, which is assumed). Each hash key is the name of a property or attribute of the object. The value for a hash key is another anonymous hash containing the following keys:

name

The name of the property or attribute. Is the same as the hash key when an anonymous hash is returned.

disp

The display name of the property or attribute.

get_meth

A reference to the method that will retrieve the value of the property or attribute.

get_args

An anonymous array of arguments to pass to a call to get_meth in order to retrieve the value of the property or attribute.

set_meth

A reference to the method that will set the value of the property or attribute.

set_args

An anonymous array of arguments to pass to a call to set_meth in order to set the value of the property or attribute.

type

The type of value the property or attribute contains. There are only three types:

short

date

blob

len

If the value is a 'short' value, this hash key contains the length of the field.

search

The property is searchable via the list() and list_ids() methods.

req

The property or attribute is required.

props

An anonymous hash of properties used to display the property or attribute. Possible keys include:

type
