Name

Bric::Biz::Asset::Business::Media - The parent class of all media objects

Synopsis

use Bric::Biz::Asset::Business::Media;

Description

Media contains all of the data that will result in published media files. It contains the metadata and associations with media documents. It inherits from Bric::Biz::Asset::Business

Interface

Constructors

$media = Bric::Biz::Asset::Business::Media->new( $initial_state )

This will create a new media object with an optionally defined initial state

Supported Keys:

Throws: NONE.

Side Effects: NONE.

Notes: NONE.

$pkg = Bric::Biz::Asset::Business::Media->cache_as

Returns "Bric::Biz::Asset::Business::Media", so that even objects blessed into a subclass of the media class will use the same package name when they're cached.

$media = Bric::Biz::Asset::Business::Media->lookup( { id => $id })

This will return a media asset that matches the criteria defined

Throws: NONE.

Side Effects: NONE.

Notes: Inherited from Bric::Biz::Asset.

(@media || $media) = Bric::Biz::Asset::Business::Media->list($param);

returns a list or list ref of media objects that match the criteria defined

Supported Keys:

title

The title of the media document. May use ANY for a list of possible values.

name

Same as title.

description

Media Document description. May use ANY for a list of possible values.

id

The media document ID. May use ANY for a list of possible values.

uuid

The media document UUID. May use ANY for a list of possible values.

exclude_id

A media document ID to exclude from the list. May use ANY for a list of possible values.

version

The media document version number. May use ANY for a list of possible values.

version_id

The ID of a version of a media document. May use ANY for a list of possible values.

file_name

The media document file name. May use ANY for a list of possible values.

user_id

Returns the versions that are checked out by the user, otherwise returns the most recent version. May use ANY for a list of possible values.

checked_out

A boolean value indicating whether to return only checked out or not checked out media.

checked_in

If passed a true value, this parameter causes the checked in version of the most current version of the media document to be returned. When a media document is checked out, there are two instances of the current version: the one checked in last, and the one currently being edited. When the checked_in parameter is a true value, then the instance last checked in is returned, rather than the instance currently checked out. This is useful for users who do not currently have a media document checked out and wish to see the media document as of the last check in, rather than as currently being worked on in the current checkout. If a media document is not currently checked out, this parameter has no effect.
