public interface BatchUpdateOp
extends RepoOnlyOp
```
Interface for BatchUpdate operations that touch a change.
Each operation has updateChange(ChangeContext) called once the change is read in a transaction. Ops are associated with updates via BatchUpdate.addOp(com.google.gerrit.entities.Change.Id, BatchUpdateOp).
Usually, a single BatchUpdateOp instance is only associated with a single change, i.e. addOp is only called once with that instance. Additionally, each method in BatchUpdateOp is called at most once per BatchUpdate execution.
Taken together, these two properties mean an instance may communicate between phases by storing data in private fields, and a single instance must not be reused.
