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.
