Handel::Checkout::Stash(3)

NAME
Handel::Checkout::Stash - Basic storage for checkout plugins during processing

SYNOPSIS
    use Handel::Checkout;

    my $checkout = Handel::Checkout->new;
    $checkout->process;

    # later in some plugin
    sub myhandler {
        my ($self, $ctx) = @_;

        $ctx->stash->{'mystuff'};
        ...
    };

    # later in some other plugin
    sub myhandler {
        my ($self, $ctx) = @_;

        my $stuff = $ctx->stash->{'mystuff'};
        ...
    };

DESCRIPTION
Handel::Checkout::Stash is used by Handel::Checkout::Plugin plugins to pass data between themselves during a call to "process". Before and after each call to process, "clear" is called is empty the stash.

To prevent this behavior, simply subclass this package with an empty clear and tell Handel::Checkout to use the new stash instead:

    package MyApp::Stash;
    use strict;
    use warnings;
    use base 'Handel::Checkout::Stash';

    sub clear {};

    ---

    use Handel::Checkout;

    my $co = Handel::Checkout->new({
        stash => MyApp::Stash->new
    });

CONSTRUCTOR

  new

Arguments: \%data

Creates a new instance of Handel::Checkout::Stash. You can optionally pass a hash reference to new which will be blessed into the new stash instance.

METHODS

  clear
Empties the contents of the stash.

The method is called before the call to $plugin->setup so plugins can set stash data, and the stash remains until the next call to process so $plugin->teardown can read any remaining stash data before "process" ends.
