+
+=head1 SYNOPSIS
+
+ # in PriceSource::Base implementation
+ $price = SL::PriceSource::Price->new(
+ price => 10.3,
+ spec => '10.3', # something you can easily parse later
+ description => t8('Fix price 10.3'),
+ price_source => $self,
+ )
+
+ # special empty price in SL::PriceSource
+ SL::PriceSource::Price->new(
+ description => t8('None (PriceSource)'),
+ );
+
+ # invalid price
+ SL::PriceSource::Price->new(
+ price => $original_price,
+ spec => $original_spec,
+ description => $original_description,
+ invalid => t8('Offer expired #1 weeks ago', $dt->delta_weeks),
+ price_source => $self,
+ );
+
+ # missing price
+ SL::PriceSource::Price->new(
+ price => $original_price, # will keep last entered price
+ spec => $original_spec,
+ description => '',

+
+=head1 DESCRIPTION
+
+See L<SL::PriceSource> for information about the mechanism.
+
+This is a container for prices that are generated by L<SL::PriceSource::Base>
+implementations.
+
+=head1 CONSTRUCTOR FIELDS
+
+=over 4
+
+=item C<price>
+
+The price. A price of 0 is special and is considered undesirable. If passed as
+part of C<available_prices> it will be filtered out. If returned as
+C<best_price> or C<price_from_source> it will be warned about.
+
+=item C<spec>
+
+A unique string that can later be understood by the creating implementation.
+Can be empty if the implementation only supports one price for a given
+record_item.
+
+=item C<description>
+
+A localized short description of the origins of this price.
+
+=item C<price_source>
+
+A ref to the creating algorithm.
+
+=item C<missing>
+
+OPTIONAL. Both indicator and localized message that the price with this spec
+could not be reproduced and should be changed.
+
+=item C<invalid>
+
+OPTIONAL. Both indicator and localized message that the conditions for this
+price are no longer valid, and that the price should be changed.
