30
|
|
|
|
|
|
|
|
31
|
|
|
|
|
|
|
This role makes a stronger promise than L<KiokuDB::Role::Immutable>, namely |
32
|
|
|
|
|
|
|
that this object and all objects it points to are immutable. |
33
|
|
|
|
|
|
|
|
34
|
|
|
|
|
|
|
These objects can be freely cached as live instances, since none of the data |
35
|
|
|
|
|
|
|
they keep live is ever updated. |
