NAME

Validation::Class::Exporter - Simple Exporter for Validation::Class Classes

VERSION

version 7.900057

SYNOPSIS

    package MyApp::Validator;

    use Validation::Class;
    use Validation::Class::Exporter;

    my @settings = (
        classes => [
            MyApp::Validator::DomainAlpha
            MyApp::Validator::DomainBeta
        ]
    );

    Validation::Class::Exporter->apply_spec(
        routines => ['thing'], # export additional routines as is
        settings => [@settings] # passed to the `load` keyword in V::C
    );

    sub thing {

        my $args = pop;

        my $class = shift || caller;

        # routine as a keyword

        # ... do some thing

    };

... in your application class:

    package MyApp;

    use MyApp::Validator;

    thing ['a', 'b'];

... in your application:

    package main;

    my $app = MyApp->new;

DESCRIPTION

This module (while experimental) encapsulates the exporting of keywords and routines. It applies the Validation::Class framework along with any keyword routines and/or sub-routines specified with the apply_spec() method. It does this by simply by copying the spec into the calling class.

To simplify writing exporter modules, "Validation::Class::Exporter" also imports "strict" and "warnings" into your exporter module, as well as into modules that use it.

METHODS

apply_spec

When you call this method, "Validation::Class::Exporter" builds a custom "import" method on the calling class. The "import" method will export the functions you specify, and can also automatically export "Validation::Class" making the calling class a Validation::Class derived class.

This method accepts the following parameters:

routines => [ ... ]
This list of function names only will be exported into the calling class exactly as is, the functions can be used traditionally or as keywords so their parameter handling should be configured accordingly.
settings => [ ... ]
This list of key/value pair will be passed to the load method imported from "Validation::Class::load" and will be applied on the calling class.

This approach affords you some trickery in that you can utilize the load method to apply the current class' configuration to the calling class' configuration, etc.
