Config::Model::Value::LayeredInclude(3pm)

NAME
Config::Model::Value::LayeredInclude - Include a sub layer configuration

VERSION
version 2.159

SYNOPSIS
    # in a model declaration:
    'element' => [
      'include' => {
        'class' => 'Config::Model::Value::LayeredInclude',

        # usual Config::Model::Value parameters
        'type' => 'leaf',
        'value_type' => 'uniline',
        'convert' => 'lc',
        'summary' => 'Include file for cascaded configuration',
        'description' => 'To support multiple variants of ...'
      },
    ]

DESCRIPTION
This class inherits from Config::Model::Value. It overrides _store to trigger a refresh of layered value when a value is changed. I.e. changing this value trigger a reload of the referred configuration file which values are used as default value. This class was designed to cope with late multistrap configuration.

  CAUTION
A configuration file can support 2 kinds of include:

•   Layered include which sets default values like default values for ssh configuration. These includes are read-only.

•   Real includes like "apache". In this cases modified configuration items can be written to included files.

This class works only with the first type
