NAME

       KiokuDB::Role::Immutable - A role for objects that are never updated.

VERSION

       version 0.57

SYNOPSIS

           with qw(KiokuDB::Role::Immutable);

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 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);
