All Implemented Interfaces:

java.io.Serializable, Policy
```
public final class DefaultPolicyWithSeparatePass
extends java.lang.Object
implements Policy
```
A simple example policy to demonstrate a policy with a separate, refactored pass. It simply performs what is done with the default pass. This example simply shows that users can define their own pass in their policy.
