/**

|
* Class Product
|
|
* Products that are available to sale, and appear on invoices.
|
|
*
|
|
* Products have one Type (Product/*), made of an Offering (Supplier/*) from a Supplier.
|
|
* Conversely, Suppliers provide Offerings (Supplier/*) which belong to a Type (Product/*) of a Product.
|
|
*
|
|
* So each product attribute has:
|
|
* + supplied : Supplier product provided for this offering (Supplier/*)
|
|
* + type : Returns the underlying product object, representing the type of product (Product/*)
|
|
*
|
|
* Attributes for products:
|
|
* + lid : Local ID for product (part number)
|
|
* + sid : System ID for product (part number)
|
|
* + base_charge : Default billing amount
|
|
* + billing_interval : Default Billing Interval
|
|
* + billing_interval_string: Default Billing Interval in human-readable form
|
|
* + category : Type of product supplied
|
|
* + category_name : Type of product supplied (Friendly Name for display, not for internal logic)
|
|
* + description : Product description (description.description_full => description_full)
|
|
* + min_charge : Minimum charge taking into account billing interval and setup charges
|
|
* + name : Details of our product (description.description_short => name_detail)
|
|
* + pid : Product ID for our Product (description.name => name_short)
|
|
* + setup_charge : Charge to setup this product
|
|
* + supplier : Supplier for this offering
|
|
*
|
|
* Attributes for product types (type - Product/*)
|
|
* + name : Short Name for our Product
|
|
* + name_long : Long Name for our Product
|
|
* + description : Description of offering (Broadband=speed)
|
|
*
|
|
* Attributes for supplier's offerings (type->supplied - Supplier/*)
|
|
* + name : Short Name for suppliers offering
|
|
* + name_long : Long Name for suppliers offering
|
|
* + description : Description of offering (Broadband=speed)
|
|
*
|
|
* Product Pricing self::pricing is an array of:
|
|
* [
|
|
* timeperiod => [
|
|
* show => true|false (show this time period to the user for ordering)
|
|
