class ProductPositions
class << self
# Provides output of a products position within a collection
# of categories. Called with just `product_id`, will lookup and return
# positions in all categories.
#
# Optionally, pass in `categories` or `category_ids` and positions for
# only these categories will be returned.
#
# It can be useful for performance to pass categories in `categories`
# and avoid the extra query.
#
# @param product_id [String]
# @param categories [Array<Workarea::Catalog::Category>]
# @param category_ids [Array<String>]
