Examples of hudson.BulkChange

hudson.BulkChange
Transaction-like object that can be used to make a bunch of changes to an object, and defer the {@link Saveable#save()} until the end.
The usage of {@link BulkChange} needs to follow a specific closure-like pattern, namely:
```
 BulkChange bc = new BulkChange(someObject); try { ... make changes to 'someObject' } finally { bc.commit(); } 
```
... or if you'd like to avoid saving when something bad happens:
```
 BulkChange bc = new BulkChange(someObject); try { ... make changes to 'someObject' bc.commit(); } finally { bc.abort(); } 
```
Use of this method is optional. If {@link BulkChange} is not used, individual mutatorwill perform the save operation, and things will just run somewhat slower.
Cooperation from {@link Saveable}

For this class to work as intended, {@link Saveable} implementations need to co-operate.Namely,
1. Mutater methods should invoke {@code this.save()} so that if the method is called outsidea {@link BulkChange}, the result will be saved immediately.
2. In the {@code save()} method implementation, use {@link #contains(Saveable)} andonly perform the actual I/O operation when this method returns false.
See {@link jenkins.model.Jenkins#save()} as an example if you are not sure how to implement {@link Saveable}. @author Kohsuke Kawaguchi @since 1.249
