LabelNormalizer (Gerrit Review Plugin API Documentation)

java.lang.Object
- com.google.gerrit.server.git.LabelNormalizer

```
public class LabelNormalizer
extends java.lang.Object
```
Normalizes votes on labels according to project config and permissions.
Votes are recorded in the database for a user based on the state of the project at that time: what labels are defined for the project, and what the user is allowed to vote on. Both of those can change between the time a vote is originally made and a later point, for example when a change is submitted. This class normalizes old votes against current project configuration.
