KeepCommand (Apache Commons Collections 4.2 API)

- org.apache.commons.collections4.sequence.EditCommand<T>
- - org.apache.commons.collections4.sequence.KeepCommand<T>

```
public class KeepCommand<T>
extends EditCommand<T>
```
Command representing the keeping of one object present in both sequences.
When one object of the first sequence equals another objects in the second sequence at the right place, the edit script transforming the first sequence into the second sequence uses an instance of this class to represent the keeping of this object. The objects embedded in these type of commands always come from the first sequence.
