Bric::Biz::Workflow - Controls the progress of an asset through a series of desks. $LastChangedRevision$ $LastChangedDate: 2005-08-19 20:54:48 +0200 (Fri, 19 Aug 2005) $ my $flow = new Bric::Biz::Workflow($param); $id = $flow->get_id; $name = $flow->get_name; $flow = $flow->set_name($name); $site_id = $flow->get_site_id; $flow = $flow->set_site_id($site_id); $desc = $flow->get_description; $flow = $flow->set_description($desc); $flow = $flow->add_desk($param); # Returns a list of allowed desks. @desks = $flow->allowed_desks(); # Lists the required desks @desks = $flow->required_desks(); A workflow is something that guides an asset through a set of desks, where an asset is any kind of creative content (a story, an image, a sound file, etc) and a desk performs and kind of validation or transformation upon an asset needed before it can be published. Example desks might be a 'legal' desk where users can verify any legal issue for a particular asset, or an 'edit' desk where users can check consistancy and presentation for an asset. A workflow might be as simple as a linear path through a set of desks or as complex as requiring certain desks be visited with other desks optional and a route through the desks that can be arbitrarily complex.

Constructors

Public Class Methods
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: The name of the property or attribute. Is the same as the hash key when an anonymous hash is returned. The display name of the property or attribute. A reference to the method that will retrieve the value of the property or attribute. An anonymous array of arguments to pass to a call to get_meth in order to retrieve the value of the property or attribute. A reference to the method that will set the value of the property or attribute. An anonymous array of arguments to pass to a call to set_meth in order to set the value of the property or attribute. The type of value the property or attribute contains. There are only three types: If the value is a 'short' value, this hash key contains the length of the field. The property is searchable via the list() and list_ids() methods. The property or attribute is required. An anonymous hash of properties used to display the property or attribute. Possible keys include: The display field type. Possible values are The Length, in letters, to display a text or password field. The maximum length of the property or value - usually defined by the SQL DDL. The number of rows to format in a textarea field. The number of columns to format in a textarea field. 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.
