NAME

Bolts::Blueprint::BuiltInjector - An injector-oriented builder using a subroutine

VERSION

version 0.143170

SYNOPSIS

use Bolts;

# Using the usual sugar...
artifact thing => (
    ...
    parameters => {
        thing => builder {
            my ($self, $bag, $name, %params) = @_;
            return MyApp::Thing->new(%params);
        },
    },
);

# Or directly...
my $meta = Bolts::Bag->start_bag;

my $artifact = Bolts::Artifact->new(
    ...
    injectors => [
        $meta->locator->acquire('injector', 'parameter_name', {
            key       => 'thing',
            blueprint => $meta->locator->acquire('blueprint', 'built_injector', {
                builder => sub {
                    my ($self, $bag, $name, %params) = @_;
                    return MyApp::Thing->new(%params);
                },
            }),
        }),
    ],
);

DESCRIPTION

This is a blueprint for using a subroutine to fill in an injected artifact dependency.

This differs from Bolts::Blueprint::Built in that it implements Bolts::Blueprint::Role::Injector, which tags this has only accepting named parameters to the builder method, which is required during injection.
