        #                  },

        #       };

DESCRIPTION

       This module is used directly by Config::Model::Node to dump the content of a configuration
       tree in perl data structure.

       The perl data structure is a hash of hash. Only CheckList content will be stored in an
       array ref.

       Note that undefined values are skipped for list element. I.e. if a list element contains
       "('a',undef,'b')", the data structure will contain 'a','b'.

CONSTRUCTOR

   new ( )
       No parameter. The constructor should be used only by Config::Model::Node.

Methods

   dump_as_data(...)
       Return a perl data structure

       Parameters are:

       node
           Reference to a Config::Model::Node object. Mandatory

       full_dump
           Also dump default values in the data structure. Useful if the dumped configuration
           data will be used by the application. (default is yes)

       skip_auto_write
           Skip node that have a "perl write" capability in their model. See
           Config::Model::BackendMgr.

       auto_vivify
           Scan and create data for nodes elements even if no actual data was stored in them.
           This may be useful to trap missing mandatory values.

       ordered_hash_as_list
           By default, ordered hash (i.e. the order of the keys are important) are dumped as Perl
           list. This is the faster way to dump such hashed while keeping the key order. But it's
           the less readable way.

           When this parameter is 1 (default), the ordered hash is dumped as a list:

             [ A => 'foo', B => 'bar', C => 'baz' ]

           When this parameter is set as 0, the ordered hash is dumped with a special key that
           specifies the order of keys. E.g.:

             { __order => [ 'A', 'B', 'C' ] ,
               B => 'bar', A => 'foo', C => 'baz'
             }

Methods

   dump_annotations_as_pod(...)
       Return a string formatted in pod (See perlpod) with the annotations.

       Parameters are:

       node
           Reference to a Config::Model::Node object. Mandatory

       experience
           master, advanced or beginner

       check_list
           Yes, no or skip
