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

VERSION
       version 7.70

SYNOPSIS
	   package MyApp::Class;

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

	   Validation::Class::Exporter->apply_spec(
	       routines => ['thing'], # export routines as is
	       settings => [ ... ] # passed to the "load" method, see Validation::Class
	   );

	   has foo => 0;

	   bld sub {

	       shift->foo(1);

	   };

	   sub thing {

	       my $args = pop;

	       my $class = shift || caller;

	       # routine as a keyword

	       $class->{config}->{THING} = [$args];

	   };

	   package MyApp::Example;

	   use MyApp::Class;

	   thing ['this' => 'that'];

	   package main;

	   my $eg = MyApp::Example->new; # we have lift-off!!!

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.
