DESCRIPTION

This module provides an object that read and write annotations (a bit like comments) to and from a configuration tree and save them in a file (not configuration file)

Depending on the effective id of the process, the annotation is saved in:

• "/var/lib/config-model/<model_name>-note.yml" for root (EUID == 0)
• "~/.config-model/<model_name>-note.yml" for normal user (EUID > 0)

CONSTRUCTOR

Quite standard. The constructor is passed a Config::Model::Instance object.

METHODS

save()

Save annotations in a file (See DESCRIPTION)

load()

Loads annotations from a file (See DESCRIPTION)
