Name

Bric::Biz::OutputChannel::Element - Maps Output Channels to Element Types.

Synopsis

use Bric::Biz::OutputChannel::Element;

# Constructors.
my $oce = Bric::Biz::OutputChannel->new($init);
my $oces_href = Bric::Biz::OutputChannel->href($params);

# Instance methods.
my $element_type_id = $oce->get_element_type_id;
$oce->set_element_type_id($element_type_id);
$oce->set_enabled_on;
$oce->set_enabled_off;
if ($oce->is_enabled) { } # do stuff.
$oce->save;

Description

This subclass of Bric::Biz::OutputChannel manages the relationship between output channels and elements (Bric::Biz::ElementType objects). It does so by providing accessors to properties relevant to the relationship, as well as an href() method to help along the use of a Bric::Util::Coll object.

Interface

This class inherits the majority of its interface from Bric::Biz::OutputChannel. Only additional methods are documented here.

Constructors

my $oce = Bric::Biz::OutputChannel::Element->new($init);
Constructs a new Bric::Biz::OutputChannel::Element object intialized with the values in the $init hash reference and returns it. The suported values for the $init hash reference are the same as those supported by Bric::Biz::OutputChannel::Element->new, with the addition of the following:
- oc_id
  The ID of the output channel object on which the new Bric::Biz::OutputChannel::Element will be based. The relevant Bric::Biz::OutputChannel object will be looked up from the database. Note that all of the $init parameters documented in Bric::Biz::OutputChannel will be ignored if this parameter is passed.
- oc
  The output channel object on which the new Bric::Biz::OutputChannel::Element will be based. Note that all of the $init parameters documented in Bric::Biz::OutputChannel will be ignored if this parameter is passed.
- element_type_id
  The ID of the Bric::Biz::ElementType object to which this output channel is mapped.
- enabled
  A boolean value indicating whether the output channel will have assets output to it by default.
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: If you pass in an output channel object via the oc parameter, that output channel object will be converted into a Bric::Biz::OutputChannel::Element object.

Notes: NONE.
my $oce_href = Bric::Biz::OutputChannel::Element->href({ element_type_id => $eid });
Returns a hash reference of Bric::Biz::OutputChannel::Element objects. Each hash key is a Bric::Biz::OutputChannel::Element ID, and the values are the corresponding Bric::Biz::OutputChannel::Element objects. Only a single parameter argument is allowed, element_type_id, though ANY may be used to specify a list of element type IDs. All of the output channels associated with that element type ID will be returned.

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.
