NAME

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

VERSION

version 2.041

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_cb to trigger a refresh of layered value when value is actually changed. I.e. changing this value will reload the refered configuration file and use its values as default value. This class was designed to cope with multistrap configuration.

CAUTION

A configuration file can support 2 kinds of include:

  • Layered include which sets default values like multistrap or ssh. 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
