VERSION

version 2.087

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 refered configuration file which values are used as default value. This class was designed to cope with multistrap <http://wiki.debian.org/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
