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 thesetText,setContent, orsetDataHandlermethods.- Since:
