perl v5.36.0                                       2023-01-07                     Mixin::ExtraFields::Param(3pm)

       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.

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.

       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.

         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;
