NAME

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

CONTENTS

VERSION

version 7.900056

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:
o 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.

o 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.
