aoqi@0 | 45 | /** |
aoqi@0 | 46 | * InternetHeaders is a utility class that manages RFC822 style |
aoqi@0 | 47 | * headers. Given an RFC822 format message stream, it reads lines |
aoqi@0 | 48 | * until the blank line that indicates end of header. The input stream |
aoqi@0 | 49 | * is positioned at the start of the body. The lines are stored |
aoqi@0 | 50 | * within the object and can be extracted as either Strings or |
aoqi@0 | 51 | * {@link Header} objects. <p> |
aoqi@0 | 52 | * <p/> |
aoqi@0 | 53 | * This class is mostly intended for service providers. MimeMessage |
aoqi@0 | 54 | * and MimeBody use this class for holding their headers. <p> |
aoqi@0 | 55 | * <p/> |
aoqi@0 | 56 | * <hr> <strong>A note on RFC822 and MIME headers</strong><p> |
aoqi@0 | 57 | * <p/> |
aoqi@0 | 58 | * RFC822 and MIME header fields <strong>must</strong> contain only |
aoqi@0 | 59 | * US-ASCII characters. If a header contains non US-ASCII characters, |
aoqi@0 | 60 | * it must be encoded as per the rules in RFC 2047. The MimeUtility |
aoqi@0 | 61 | * class provided in this package can be used to to achieve this. |
aoqi@0 | 62 | * Callers of the <code>setHeader</code>, <code>addHeader</code>, and |
aoqi@0 | 63 | * <code>addHeaderLine</code> methods are responsible for enforcing |
aoqi@0 | 64 | * the MIME requirements for the specified headers. In addition, these |
aoqi@0 | 65 | * header fields must be folded (wrapped) before being sent if they |
aoqi@0 | 66 | * exceed the line length limitation for the transport (1000 bytes for |
aoqi@0 | 67 | * SMTP). Received headers may have been folded. The application is |
aoqi@0 | 68 | * responsible for folding and unfolding headers as appropriate. <p> |
