54 |
* This class represents a MIME body part.
|
|
55 |
* MimeBodyParts are contained in <code>MimeMultipart</code>
|
|
56 |
* objects. <p>
|
|
57 |
*
|
|
58 |
* MimeBodyPart uses the <code>InternetHeaders</code> class to parse

59 |

|
|
61 |
* <hr><strong>A note on RFC 822 and MIME headers</strong><p>
|
|
62 |
*
|
|
63 |
* RFC 822 header fields <strong>must</strong> contain only
|
|
64 |
* US-ASCII characters. MIME allows non ASCII characters to be present
|
|
65 |
* in certain portions of certain headers, by encoding those characters.
|
|
66 |
* RFC 2047 specifies the rules for doing this. The MimeUtility
|
|
67 |
* class provided in this package can be used to to achieve this.
|
|
68 |
* Callers of the <code>setHeader</code>, <code>addHeader</code>, and
|
|
69 |
* <code>addHeaderLine</code> methods are responsible for enforcing
|
|
70 |
* the MIME requirements for the specified headers. In addition, these
|
|
71 |
* header fields must be folded (wrapped) before being sent if they
|
|
72 |
* exceed the line length limitation for the transport (1000 bytes for
|
|
73 |
* SMTP). Received headers may have been folded. The application is
|
|
74 |
* responsible for folding and unfolding headers as appropriate. <p>
