=head1 NAME
KiokuDB::Role::Immutable - A role for objects that are never updated.
=head1 VERSION
version 0.57
=head1 SYNOPSIS
with qw(KiokuDB::Role::Immutable);
=head1 DESCRIPTION
This is a role for objects that are never updated after they are inserted to
the database.
The object will be skipped entirely on all update/store operations unless it is
being collapsed for the first time, and its child objects will B<not> be
updated unless they are found while collapsing another object.
This means that:
my $immutable = $kiokudb->lookup($id);
$immutable->child->name("foo");
$kiokudb->update($immutable);
will not work, you need to update the child directly:
$kiokudb->update($immutable->child);
