```
public interface IRevisionCriteria
```

Implement this interface if you want to control when certain [Revision](../../com.aspose.words/revision/) should be accepted/rejected or not by the [RevisionCollection.accept(com.aspose.words.IRevisionCriteria)](../../com.aspose.words/revisioncollection/\#accept-com.aspose.words.IRevisionCriteria)/ [RevisionCollection.reject(com.aspose.words.IRevisionCriteria)](../../com.aspose.words/revisioncollection/\#reject-com.aspose.words.IRevisionCriteria) methods.

 **Examples:** 

Shows how to accept or reject revision based on criteria.

```

 public void revisionSpecifiedCriteria() throws Exception
 {
     Document doc = new Document();
     DocumentBuilder builder = new DocumentBuilder(doc);
     builder.write("This does not count as a revision. ");

     // To register our edits as revisions, we need to declare an author, and then start tracking them.
     doc.startTrackRevisions("John Doe", new Date());
     builder.write("This is insertion revision #1. ");
     doc.stopTrackRevisions();

     doc.startTrackRevisions("Jane Doe", new Date());
     builder.write("This is insertion revision #2. ");
     // Remove a run "This does not count as a revision.".
     doc.getFirstSection().getBody().getFirstParagraph().getRuns().get(0).remove();
