NAME

Config::Model::Itself::BackendDetector - Detect available read/write backends

SYNOPSIS

# this class should be referenced in a configuration model and
# created only by Config::Model::Node

my $model = Config::Model->new() ;

$model ->create_config_class
 (
  name => "Test",
  'element'
  => [ 
      'backend' => { type => 'leaf',
                     class => 'Config::Model::Itself::BackendDetector' ,
                     value_type => 'enum',
                     # specify backends built in Config::Model
                     choice => [qw/cds_file perl_file ini_file custom/],

                     help => {
                              cds_file => "file ...",
                              ini_file => "Ini file ...",
                              perl_file => "file  perl",
                              custom => "Custom format",
                             }
                   }
     ],
 );

 my $root = $model->instance(root_class_name => 'Test') -> config_root ;

 my $backend = $root->fetch_element('backend') ;

 my @choices = $backend->get_choice ;

DESCRIPTION

This class is derived from Config::Model::Value. It is designed to be used in a 'enum' value where the choice (the available backends) are the backend built in Config::Model and all the plugin backends. The plugin backends are all the Config::Model::Backend::* classes.

This module will detect available plugin backend and query their pod documentation to provide a contextual help for config-model graphical editor.
