NAME

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

VERSION

       version 0.022

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.

PERL VERSION

       This library should run on perls released even a long time ago.  It should work on any
       version of perl released in the last five years.

       Although it may work on older versions of perl, no guarantee is made that the minimum
       required version will not be increased.  The version may be increased for any reason, and
       there is no promise that patches will be accepted to lower the minimum required perl.

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.
