NAME

Config::Model::DumpAsData - Dump configuration content as a perl data structure

VERSION

version 1.208

SYNOPSIS

 use Config::Model ;

 # create your config model
 my $model = Config::Model -> new ;
 $model->create_config_class( ... ) ;

 # create instance
 my $inst = $model->instance (root_class_name => 'FooBar', 
                              instance_name => 'test1');

 # create root of config
 my $root = $inst -> config_root ;

 my $data =  $root->dump_as_data ;

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 capabality in their model. See Config::Model::AutoRead.

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 parmeter 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' 
  }
