KiokuDB::Role::Immutable - A role for objects that are never updated.
with qw(KiokuDB::Role::Immutable);
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);
To install KiokuDB, copy and paste the appropriate command in to your terminal.
