use WebGUI::Shop::Pay;
=head1 METHODS
These subroutines are available from this package:
=cut
#-------------------------------------------------------------------
=head2 session ()
Returns a reference to the current session.
=cut
has session => (
is => 'ro',
required => 1,
);
around BUILDARGS => sub {
my $orig = shift;

##Original arguments start here.

}

};
#-------------------------------------------------------------------
=head2 addPaymentGateway ( $class, $label, $options )

back up to the top.
=head4 $class
The class of the new PayDriver object to create.
=head4 $options
A list of properties to assign to this PayDriver. See C<definition> for details.
=cut

#-------------------------------------------------------------------
=head2 getDrivers ( )
This subroutine returns a hash reference of available shipping driver classes as keys with their human readable names as values, read from the WebGUI config file in the shippingDrivers directive.
=cut

#-------------------------------------------------------------------
=head2 getOptions ( $cart )
Returns a set of options for the user to pay to. It is a hash of
gatewayIds and labels.
The hash will only contain payment gateways that this user is allowed to use.
=head3 $cart
A WebGUI::Shop::Cart object. A WebGUI::Error::InvalidParam exception will be thrown if it doesn't get one.
=cut

}
#-------------------------------------------------------------------
=head2 getPaymentGateway ( $id )
Looks up an existing PayDriver in the db by paymentGatewayId and returns
that object. If the PayDriver throws an exception, it is propagated
back up to the top.
=head3 id
The id of the gateway to instanciate.
=cut
sub getPaymentGateway {

#-------------------------------------------------------------------
=head2 getRecurringPeriodValues ( period )
A utility method that returns the internationalized name for period.
=head3 period
The period you want the name for.

#-------------------------------------------------------------------
=head2 www_addPaymentGateway ( $session )
Add a new payment gateway, based on the className form variable. It will throw
an error, WebGUI::Error::InvalidParram if no className is passed.
=head3 $session
A reference to the current session object.
