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