It provides the base interface for the MimeMessage and MimeBodyPart classes <hr> <strong>A note on RFC822 and MIME headers</strong><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><P><P><DL><DT><B>Author:</B></DT> <DD>John Mani</DD><DT><B>See Also:</B><DD><A HREF="../../../javax/mail/internet/MimeUtility.html" title="class in javax.mail.internet"><CODE>MimeUtility</CODE></A>, <A HREF="../../../javax/mail/Part.html" title="interface in javax.mail"><CODE>Part</CODE></A></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR></TABLE> <A NAME="fields_inherited_from_class_javax.mail.Part"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface javax.mail.<A HREF="../../../javax/mail/Part.html" title="interface in javax.mail">Part</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/mail/Part.html#ATTACHMENT">ATTACHMENT</A>, <A HREF="../../../javax/mail/Part.html#INLINE">INLINE</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#addHeaderLine(java.lang.String)">addHeaderLine</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> line)</CODE><BR> Add a raw RFC822 header-line.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/Enumeration.html" title="class or interface in java.util">Enumeration</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#getAllHeaderLines()">getAllHeaderLines</A></B>()</CODE><BR> Get all header lines as an Enumeration of Strings. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#getContentID()">getContentID</A></B>()</CODE><BR> Get the Content-ID of this part. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#getContentLanguage()">getContentLanguage</A></B>()</CODE><BR> Get the language tags specified in the Content-Language header of this MimePart. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#getContentMD5()">getContentMD5</A></B>()</CODE><BR> Get the Content-MD5 digest of this part. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#getEncoding()">getEncoding</A></B>()</CODE><BR> Get the transfer encoding of this part.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/mail/internet/MimePart.html#getHeader(java.lang.String, java.lang.String)">getHeader</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> name, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> delimiter)</CODE><BR> Get the values of all header fields available for this header, returned as a single String, with the values separated by the delimiter. </TD>⌨️ 快捷键说明
