KiokuDB::Util - Utility functions for working with KiokuDB

SYNOPSIS

DESCRIPTION

This module provides various helper functions for working with KiokuDB.

EXPORTS

set

weak_set

Instantiate a Set::Object or Set::Object::Weak from the arguments, and then creates a KiokuDB::Set::Transient with the result.

import_yaml $kiokudb, @files_or_dirs

Loads YAML files with MooseX::YAML (if given a directory it will be searched recursively for files with a .yml extension are) into the specified KiokuDB directory in a single transaction.

The YAML files can contain multiple documents, with each document treated as an object. If the YAML file contains a single non blessed array or hash then that structure will be dereferenced as part of the arguments to insert.

Here is an example of an array of objects, and a custom tag alias to ease authoring of the YAML file:

%YAML 1.1
%TAG ! !MyFoo::
---
- !User
  id:        foo
  real_name: Foo Bar
  email:     foo@myfoo.com
  password:  '{cleartext}test123'

You can use a hash to specify custom IDs:

%YAML 1.1
---
the_id: !Some::Class
    attr: moose
