Handel::Checkout::Plugin
Base module for Handle::Checkout plugins

Handel::Checkout::Plugin - Base module for Handle::Checkout plugins


NAME

Handel::Checkout::Plugin - Base module for Handle::Checkout plugins


SYNOPSIS


    package MyPackage::FaxOrder;

    use Handel::Constants qw(:checkout);

    use base 'Handel::Checkout::Plugin';

    

    sub register {

        my ($self, $ctx) = @_;

        $ctx->add_handler(CHECKOUT_PHASE_DELIVER, \&deliver);

    };

    

    sub deliver {

        my ($self, $ctx) = @_;

    

        ...

    

        return CHECKOUT_HANDLER_OK;

    };


DESCRIPTION

Handel::Checkout::Plugin is the base module for all checkout pipeline plugins used in Handel::Checkout.


CONSTRUCTOR

new

Returns as new Handle::Checkout::Plugin object. This method is inherited by all subclasses and called when each plugin is loaded into the checkout pipeline. There should be no need to call this method directly.


METHODS

The following methods are called during various times in the checkout process. Each method receives a reference to its instance as well as reference to the current checkout process:


    sub init {

        my ($self, $ctx) = @_;

    };

init

This method is called then the plugin is first created and loaded into the checkout pipeline. While a pipeline can be processed more than once, init will only be called the first time the plugin is loaded.

register

After a plugin is loaded, register is called so the plugin can register itself with the various phases in the current checkout pipeline process using add_handler in Handel::Checkout:


    sub register {

        my ($self, $ctx) = @_;

        $ctx->add_handler(CHECKOUT_PHASE_DELIVER, \&deliver);

    };

A plugin can register any number of methods with any number of phases.

setup

Each time a checkout pipeline is processed, the setup method is called on all registered plugins to allow each plugin to perform any necessary preparation before its registered handler subs are called.

teardown

Each time a checkout pipeline is finished being processed, the teardown method is called on all registered plugins to allow each plugin to perform any cleanup it may need to do.

name

Returns the name of the current instance.
