$oc = Bric::Biz::OutputChannel->new( $initial_state )

Instantiates a Bric::Biz::OutputChannel object. An anonymous hash of initial values may be passed. The supported initial value keys are:

name
description
primary
active (default is active, pass undef to make a new inactive Output Channel)

Throws: NONE.

Side Effects: NONE.

Notes: NONE.

$oc = Bric::Biz::OutputChannel->lookup({ id => $id })

$oc = Bric::Biz::OutputChannel->lookup({ name => $name })

Looks up and instantiates a new Bric::Biz::OutputChannel object based on an Bric::Biz::OutputChannel object ID or name. If no output channelobject is found in the database, lookup() returns undef.

Throws:

Missing required parameter 'id' or 'name'.
Unable to connect to database.
Unable to prepare SQL statement.
Unable to select column into arrayref.
Unable to execute SQL statement.

Side Effects: NONE.

Notes: NONE.

($ocs_aref || @ocs) = Bric::Biz::OutputChannel->list( $criteria )

Returns a list or anonymous array of Bric::Biz::OutputChannel objects based on the search parameters passed via an anonymous hash. The supported lookup keys are:

name
description
primary
server_type_id
include_parent_id
story_instance_id

Public Class Methods

($id_aref || @ids) = Bric::Biz::OutputChannel->list_ids( $criteria )

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

my $meths = Bric::Biz::OutputChannel->my_meths

my (@meths || $meths_aref) = Bric::Biz::OutputChannel->my_meths(TRUE)

my (@meths || $meths_aref) = Bric::Biz::OutputChannel->my_meths(0, TRUE)

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 id, 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.
