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