Set::Object::Weak(3)					User Contributed Perl Documentation				      Set::Object::Weak(3)

NAME

       Set::Object::Weak - Sets without the referant reference increment

SYNOPSIS

	use Set::Object::Weak qw(weak_set);

	my $set = Set::Object::Weak->new( 0, "", {}, [], $object );
	# or
	my $set = weak_set( 0, "", {}, [], $object );

	print $set->size;  # 2 - the scalars aren't objects

DESCRIPTION

       Sets, but weak.	See "weaken" in Set::Object.

       Note that the "set" in "Set::Object::Weak" returns weak sets.  This is intentional, so that you can make all the sets in scope weak just by
       changing "use Set::Object" to "use Set::Object::Weak".

CONSTRUCTORS

       new This class method is exactly the same as "Set::Object->new", except that it returns a weak set.

       weak_set( ... )
	   This optionally exported function is a shortcut for saying "Set::Object::Weak->new(...)".

       set( ... )
	   This method is exported so that if you see:

	    use Set::Object qw(set);

	   You can turn it into using weak sets lexically with:

	    use Set::Object::Weak qw(set);

	   Set::Object 1.19 had a bug in this method that meant that it would not add the passed members into it.

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
