/**
* <p> Filter marking interface for filter ordering. </p>
*
* <h3>Input order</h3>
*
* <p> On input filter chains the consumer is at the user end,
* opposite the source. </p>
*
*
* <h3>Output order</h3>
*
* <p> On output filter chains the consumer is at the target end,
* opposite the producer. </p>
*
*
* <h3>Example</h3>
*
* <p> The {@link oaep$dec} filter is an example of a consumer. In
* decoding it is useful only as the last transformer on the data, a
* role necessarily symmetric to its use in the encoding
* direction. </p>
*
* <p> The {@link base64$enc} filter is an example of a consumer. In
* encoding it is useful only as the last transformer on the data.
* The Base64 format has no other efficient and practical use. </p>
