The asset type class registers new type of assets that will go through work flow. The individual parts will describe how the fields of the story will be laid out.

The AssetType object is composed of AssetType Parts Data objects and AssetType Parts Container objects. These hold the fields that will become Assets when they enter workflow. Rules can be set upon these.

The AssetType object also holds what output channels this asset will be allowed to go through.

$element = Bric::Biz::AssetType->new($init)

Will return a new asset type object with the optional initial state Supported Keys:

name

key_name

description

reference

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

*

Too many Bric::Biz::AssetType objects found. Side Effects: NONE Notes: NONE This will return a list of objects that match the criteria defined. Supported Keys:

name

The name of the asset type. Matched with case-insentive LIKE.

key_name

The unique key name of the asset type. Matched with case insensitive LIKE

description

The description of the asset type. Matched with case-insentive LIKE.

output_channel_id

The ID of an output channel. Returned will be all AssetType objects that contain this output channel.

data_name

The name of an AssetType::Data object. Returned will be all AssetType objects that reference this particular AssetType::Data object.

map_type__id

The map_type__id of an AssetType::Data object.

active

Set to 0 to return active and inactive asset types. 1, the default, returns only active asset types.

type__id

match elements of a particular attype

top_level

set to 1 to return only top-level elements

media

match against a particular media asset type (att.media)

site_id

match against the given site_id Throws: NONE Side Effects: NONE Notes: NONE This will return a list of objects that match the criteria defined. See the CWlist() method for the allowed keys of the CW$param hash reference. Throws: NONE Side Effects: NONE Notes: NONE

$self->DESTROY

Dummy method to prevent wasting time trying to AUTOLOAD DESTROY.

$meths = Bric::Biz::AssetType->my_meths

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

The display field type. Possible values are

text

textarea

password

hidden

radio

checkbox

select

length

The Length, in letters, to display a text or password field.

maxlength

The maximum length of the property or value - usually defined by the SQL DDL.

rows

The number of rows to format in a textarea field.

cols

The number of columns to format in a textarea field.

vals

An anonymous hash of key/value pairs reprsenting the values and display names to use in a select list. Throws: NONE. Side Effects: NONE. Notes: NONE.

This will return the id for the database Throws: NONE Side Effects: NONE Notes: NONE This will set the name field for the asset type Throws: NONE Side Effects: NONE Notes: NONE This will return the name field for the asset type Throws: NONE Side Effects: NONE Notes: NONE This will set the unique key name field for the asset type Throws: NONE Side Effects: NONE Notes: NONE This will return the unique key name field for the asset type Throws: NONE Side Effects: NONE Notes: NONE this sets the description field Throws: NONE Side Effects: NONE Notes: NONE This returns the description field Throws: NONE Side Effects: NONE Notes: NONE This will set the primary output channel id field for the asset type Throws:

*

No site parameter passed to Bric::Biz::AssetType->set_primary_oc_id

*

No output channels associated with non top-level elements. Side Effects: NONE. Notes: NONE. This will return the primary output channel id field for the asset type Throws:

*

No site parameter passed to Bric::Biz::AssetType->get_primary_oc_id.

*

No output channels associated with non top-level elements. Side Effects: NONE. Notes: NONE. Get the type name of the asset type. Throws: NONE Side Effects: NONE Notes: NONE Get the burner associated with the asset type. Possible values are the constants BURNER_MASON and BURNER_TEMPLATE defined in this package. Throws: NONE Side Effects: NONE Notes: NONE

$at->set_burner(Bric::Biz::AssetType::BURNER_MASON);

Get the burner associated with the asset type. Possible values are the constants BURNER_MASON and BURNER_TEMPLATE defined in this package. Throws: NONE Side Effects: NONE Notes: NONE Get the type description of the asset type. Throws: NONE Side Effects: NONE Notes: NONE Return whether this is a top level story or not. Throws: NONE Side Effects: NONE Notes: NONE Return whether this asset type should produce a paginated asset or not. Throws: NONE Side Effects: NONE Notes: NONE Return whether this asset type can have related media objects. Throws: NONE Side Effects: NONE Notes: NONE Return whether this asset type can have related story objects. Throws: NONE Side Effects: NONE Notes: NONE Mark this Asset Type as representing a media object or a story object. Media objects do not support all the options that story objects to like nested containers or references, but they include options that story doesnt like autopopulated fields. The 'is_media' method returns true if this is a media object and false otherwise. The 'set_media' method marks this as a media object. It does not take any arguments, and always sets the media flag to true, so you cant do this: $at->set_media(0) and expect to set the media flag to false. To unset the media flag (set it to false) use the 'clear_media' method. Throws: NONE Side Effects: NONE Notes: NONE

$at->get_biz_class()

$at->get_biz_class_id()

$at->set_biz_class('class' => '' || 'id' => '');

The methods 'get_biz_class' and 'get_biz_class_id' get the business class name or the business class ID respectively from the class table. The 'set_biz_class' method sets the business class for this asset type given either a class name or an ID from the class table. This value represents the kind of bussiness object this asset type will represent. There are just two main kinds, story and media objects. However media objects have many subclasses, one for each type of supported media (image, audio, video, etc) increasing the number of package names this value could be set to. Throws: NONE Side Effects: NONE Notes: NONE Return whether this asset type references other data. Throws: NONE Side Effects: NONE Notes: NONE Return whether this asset type should produce a fixed url asset or not. Throws: NONE Side Effects: NONE Notes: NONE Return the at_type object associated with this element. Throws: NONE Side Effects: NONE Notes: NONE Get/Set/Delete attributes on this asset type. Throws: NONE Side Effects: NONE Notes: NONE Get/Set attribute metadata on this asset type. Calling the 'get_meta' method without '$field' returns all metadata names and values as a hash. Throws: NONE Side Effects: NONE Notes: NONE This returns a list of output channels that have been associated with this asset type. If CW@oc_ids is passed, then only the output channels with those IDs are returned, if they're associated with this asset type. Throws: NONE. Side Effects: NONE. Notes: The objects returned will be Bric::Biz::OutputChannel::Element objects, and these objects contain extra information relevant to the assocation between each output channel and this element object. Adds an output channel to this element object and returns the resulting Bric::Biz::OutputChannel::Element object. Can pass in either an output channel object or an output channel ID. Throws: NONE. Side Effects: If a Bric::Biz::OutputChannel object is passed in as the first argument, it will be converted into a Bric::Biz::OutputChannel::Element object. Notes: NONE. This accepts an array reference of output channel objects to be associated with this asset type. Throws: NONE. Side Effects: Any Bric::Biz::OutputChannel objects passed in will be converted into Bric::Biz::OutputChannel::Element objects. Notes: NONE. This takes an array reference of output channels and removes their association from the object. Throws:

*

If CW@site_ids is passed, then only the sites with those IDs are returned, if they're associated with this asset type. Throws: NONE. Side Effects: NONE. Notes: The objects returned will be Bric::Biz::Site objects, and these objects contain extra information relevant to the assocation between each output channel and this element object. Adds a site to this element object and returns the resulting Bric::Biz::Site object. Can pass in either an site object or a site ID. Throws:

*

You can only add sites to top level objects

*

Cannot add sites to non top-level elements.

*

No such site. Side Effects: NONE. Notes: NONE. Adds a site to this element object and returns the Bric::Biz::AssetType object. Can pass in multiple site objects or site IDs. Throws:

*

You can only add sites to top level objects

*

Couldn't find site Side Effects: NONE. Notes: NONE. This takes an array reference of sites and removes their association from the object. Throws:

*

This will return a list of the fields and containers that make up this asset type Throws: NONE Side Effects: NONE Notes: The parts returned here may not have their parent IDs or order set if this object has not been saved yet. This takes a list of fields and associates them with the element object Throws: NONE Side Effects: NONE Notes: NONE Adds a new data point, creating a new Bric::Biz::AssetType::Parts::Data object. The keys to CW$param are the same as the keys for the hash ref passed to Bric::Biz::AssetType::Parts::Data::new. Throws: NONE Side Effects: NONE Notes: NONE Copy the definition for a data field from another asset type. Keys for CW$param are:

*

at An existing asset type object

*

field_name A field name defined within the object passed with 'at'

*

field_obj A field object. Can be given in lieu of 'at' and 'field_name'. Throws: NONE Side Effects: NONE Notes: NONE This will take a list of parts and will disassociate them from the story type. Throws: NONE Side Effects: NONE Notes: NONE Add AssetTypes to be contained by this AssetType. Throws: NONE Side Effects: NONE Notes: NONE Return all contained AssetTypes.
