NAME
    DBIx::Class::UUIDColumns - Implicit uuid columns

SYNOPSIS
      package Artist;
      __PACKAGE__->load_components(qw/UUIDColumns Core DB/);
      __PACKAGE__->uuid_columns( 'artist_id' );

DESCRIPTION
    This DBIx::Class component resembles the behaviour of Class::DBI::UUID,
    to make some columns implicitly created as uuid.

    When loaded, "UUIDColumns" will search for a suitable uuid generation
    module from the following list of supported modules:

      Data::UUID
      APR::UUID*
      UUID
      Win32::Guidgen
      Win32API::GUID

    If no supporting module can be found, an exception will be thrown.

    *APR::UUID will not be loaded under OpenBSD due to an as yet
    unidentified XS issue.

    If you would like to use a specific module, you can set "uuid_class":

      __PACKAGE__->uuid_class('::Data::UUID');
      __PACKAGE__->uuid_class('MyUUIDGenerator');

    Note that the component needs to be loaded before Core.

METHODS
  uuid_columns(@columns)
    Takes a list of columns to be filled with uuids during insert.

      __PACKAGE__->uuid_columns('id');

  uuid_class($classname)
    Takes the name of a UUIDMaker subclass to be used for uuid value
    generation. This can be a fully qualified class name, or a shortcut name
    starting with :: that matches one of the available
    DBIx::Class::UUIDMaker subclasses:

      __PACKAGE__->uuid_class('CustomUUIDGenerator');
      # loads CustomeUUIDGenerator

      __PACKAGE->uuid_class('::Data::UUID');
      # loads DBIx::Class::UUIDMaker::Data::UUID;

    Note that "uuid_class" chacks to see that the specified class isa
    DBIx::Class::UUIDMaker subbclass and throws and exception if it isn't.

  uuid_maker
    Returns the current UUIDMaker instance for the given module.

      my $uuid = __PACKAGE__->uuid_maker->as_string;
