Mixin::ExtraFields::Param(3)

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

VERSION
version 0.021

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.
