NAME

       Mixin::ExtraFields::Param - make your class provide a familiar "param" method

VERSION

       version 0.020

SYNOPSIS

         package Widget::Parametric;
         use Mixin::ExtraFields::Param -fields => { driver => 'HashGuts' };;

         ...

         my $widget = Widget::Parametric->new({ flavor => 'vanilla' });

         printf "%s: %s\n", $_, $widget->param($_) for $widget->param;

DESCRIPTION

       This module mixes in to your class to provide a "param" method like the ones provided by
       CGI, CGI::Application, and other classes.  It uses Mixin::ExtraFields, which means it can
       use any Mixin::ExtraFields driver to store your data.

       By default, the methods provided are:

       •   param

       •   exists_param

       •   delete_param

       These methods are imported by the "fields" group, which must be requested.  If a "moniker"
       argument is supplied, the moniker is used instead of "param".  For more information, see
       Mixin::ExtraFields.

METHODS

   param
        my @params = $object->param;        # get names of existing params

        my $value = $object->param('name'); # get value of a param

        my $value = $object->param(name => $value); # set a param's value

        my @values = $object->param(n1 => $v1, n2 => $v2, ...); # set many values

       This method sets or retrieves parameters.
