=head1 NAME

KiokuDB::TypeMap::Default - A standard KiokuDB::TypeMap with predefined entries.

=head1 VERSION

version 0.56

=head1 SYNOPSIS

    # the user typemap implicitly inherits from the default one, which is
    # provided by the backend.

    my $dir = KiokuDB->new(
        backend => $b,
        typemap => $user_typemap,
    );

=head1 DESCRIPTION

The default typemap is actually defined per backend, in
L<KiokuDB::TypeMap::Default::JSON> and L<KiokuDB::TypeMap::Default::Storable>.
The list of classes handled by both is the same, but the typemap entries
themselves are tailored to the specific backend's requirements/capabilities.

The entries have no impact unless you are actually using the listed modules.

The default typemap is created using L<KiokuDB::TypeMap::Composite> and accepts
all the standard options

=head1 SUPPORTED TYPES

The following typemaps provide support for these classes:

=over 4

=item core

L<KiokuDB::Set>

=item tie

L<Tie::RefHash>, L<Tie::IxHash>

=item datetime

L<DateTime>

=item uri_typemap

L<URI>, L<URI::WithBase>

=item path_class

L<Path::Class::Entity>

=item authen_passphrase

L<Authen::Passphrase>
