- * be used to extract further information from a state.
- * <p>
- * An example scenario would be a {@link Query} that requests a web site and a
- * {@link Filter} that extracts content from the web site. That way the same
- * {@link Query} could be used for multiple {@link Reaction}s without requiring
- * modifications.
