public class PreencodedMimeBodyPart
extends MimeBodyPart

A MimeBodyPart that handles data that has already been encoded. This class is useful when constructing a message and attaching data that has already been encoded (for example, using base64 encoding). The data may have been encoded by the application, or may have been stored in a file or database in encoded form. The encoding is supplied when this object is created. The data is attached to this object in the usual fashion, by using the setText, setContent, or setDataHandler methods.

Since:

JavaMail 1.4
