NAME¶

KiokuDB::Util - Utility functions for working with KiokuDB

SYNOPSIS¶

    use KiokuDB::Util qw(set weak_set);
    my $set = set(@objects); # create a transient set
    my $weak = weak_set(@objects); # to avoid circular refs

DESCRIPTION¶

This module provides various helper functions for working with KiokuDB.

EXPORTS¶

dsn_to_backend $dsn, %args

Tries to parse $dsn, load the backend and invoke "new" on it.

 

Used by "connect" in KiokuDB and the various command line interfaces.

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
