=head1 NAME
KiokuDB::Backend::Serialize::JSON - Role to serialize entries to JSON strings with KiokuDB::Backend::Serialize::JSPON semantics
=head1 VERSION
version 0.57
=head1 SYNOPSIS
with qw(KiokuDB::Backend::Serialize::JSON);
sub foo {
my ( $self, $entry ) = @_;
my $json_string = $self->serialize($entry);
}
=head1 DESCRIPTION
This role provides additional convenience attributes and methods for backends
that encode entries to JSON strings, on top of
L<KiokuDB::Backend::Serialize::JSPON> which only restructures the data.
L<KiokuDB::Backend::Serialize::Delegate> is preferred to using this directly.
=head1 METHODS
=over 4
=item serialize $entry
Returns a JSON string
=item deserialize $json_str
Returns a L<KiokuDB::Entry>
=back
=head1 ATTRIBUTES

=item pretty
