/**

* {@link Codec}s that uses the MIME multipart as the underlying format.
|
|
*
|
|
* <p>
|
|
* When the runtime needs to dynamically choose a {@link Codec}, and
|
|
* when there are more than one {@link Codec}s that use MIME multipart,
|
|
* it is often impossible to determine the right {@link Codec} unless
|
|
* you parse the multipart message to some extent.
|
|
*
|
|
* <p>
|
|
* By having all such {@link Codec}s extending from this class,
|
|
* the "sniffer" can decode a multipart message partially, and then
|
|
* pass the partial parse result to the ultimately-responsible {@link Codec}.
|
|
* This improves the performance.
