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.
