DESCRIPTION

ATTRIBUTES

METHODS

new(%args)

Construct a new Config::Tree::Var object. Arguments.

• tree. Required. Perl data structure that contains the tree. Must be a hashref.

• ro. Optional, default is 0. Whether we should disallow set() and save().

• when_invalid. Optional, default is 'die'. What to do when file content does not validate with supplied schema. Choices: 'die', 'warn', 'quiet'.

• exclude_path_re. Optional. When set, config path matching the regex will not be retrieved. See also: include_path_re.

• include_path_re. Optional. When set, only config path matching the regex will be retrieved. Takes precedence over exclude_path_re.

• schema. Optional. When specified, after the tree is retrieved, it will be validated against this schema using Data::Schema.

set($path, $val)

Set config variable in the tree.

save()

Does nothing. set() will already modify the Perl data structure.
