All Implemented Interfaces:

Runnable

@Private
public final class ReencryptionUpdater
extends Object
implements Runnable

Class for finalizing re-encrypt EDEK operations, by updating file xattrs with edeks returned from reencryption.

The tasks are submitted by ReencryptionHandler.

It is assumed only 1 Updater will be running, since updating file xattrs requires namespace write lock, and performance gain from multi-threading is limited.
